docs(telegram): clarify group activation and access control

- Add detailed explanation of group activation modes (requireMention)
- Document /activation command (mention vs always)
- Clarify two-level access control: group allowlist + sender policy
- Add troubleshooting section for common issues
- Explain that telegram.groups creates an allowlist
- Add instructions for getting group chat ID

Fixes confusion around group setup where /activation command
updates session state but doesn't persist or take effect.

- Group replies require a mention by default (native @mention or `routing.groupChat.mentionPatterns`).
- Replies always route back to the same Telegram chat.
## Group activation modes
By default, the bot only responds to mentions in groups (`@botname` or patterns in `routing.groupChat.mentionPatterns`). To change this behavior:
### Via config (recommended)
```json5
{
telegram: {
groups: {
"-1001234567890": { requireMention: false } // always respond in this group
}
}
}
```
**Important:** Setting `telegram.groups` creates an **allowlist** - only listed groups (or `"*"`) will be accepted.
To allow all groups with always-respond:
```json5
{
telegram: {
groups: {
"*": { requireMention: false } // all groups, always respond
}
}
}
```
To keep mention-only for all groups (default behavior):
```json5
{
telegram: {
groups: {
"*": { requireMention: true } // or omit groups entirely
}
}
}
```
### Via command (session-level)
Send in the group:
- `/activation always` - respond to all messages
- `/activation mention` - require mentions (default)
**Note:** Commands update session state only. For persistent behavior across restarts, use config.
### Getting the group chat ID
Forward any message from the group to `@userinfobot` or `@getidsbot` on Telegram to see the chat ID (negative number like `-1001234567890`).
## Topics (forum supergroups)
Telegram forum topics include a `message_thread_id` per message. Clawdbot:

## Access control (DMs + groups)
### DM access
- Default: `telegram.dmPolicy = "pairing"`. Unknown senders receive a pairing code; messages are ignored until approved (codes expire after 1 hour).
- Approve via:
- `clawdbot pairing list --provider telegram`
- `clawdbot pairing approve --provider telegram <CODE>`
- Pairing is the default token exchange used for Telegram DMs. Details: [Pairing](/start/pairing)
Group gating:
- `telegram.groupPolicy = open | allowlist | disabled`.
- `telegram.groups` doubles as a group allowlist when set (include `"*"` to allow all).
### Group access
Two independent controls:
**1. Which groups are allowed** (group allowlist via `telegram.groups`):
- No `groups` config = all groups allowed
- With `groups` config = only listed groups or `"*"` are allowed
- Example: `"groups": { "-1001234567890": {}, "*": {} }` allows all groups
**2. Which senders are allowed** (sender filtering via `telegram.groupPolicy`):
- `"open"` (default) = all senders in allowed groups can message
- `"allowlist"` = only senders in `telegram.groupAllowFrom` can message
- `"disabled"` = no group messages accepted at all
Most users want: `groupPolicy: "open"` + specific groups listed in `telegram.groups`
## Long-polling vs webhook
- Default: long-polling (no public URL required).
@@ -104,6 +170,27 @@ Reasoning stream (Telegram only):
- Use a chat id (`123456789`) or a username (`@name`) as the target.
- Example: `clawdbot send --provider telegram --to 123456789 "hi"`.
## Troubleshooting
**Bot doesn't respond to non-mention messages in group:**
- Check if group is in `telegram.groups` with `requireMention: false`
- Or use `"*": { "requireMention": false }` to enable for all groups
- Test with `/activation always` command (requires config change to persist)
**Bot not seeing group messages at all:**
- If `telegram.groups` is set, the group must be listed or use `"*"`
- Check Privacy Settings in @BotFather → "Group Privacy" should be **OFF**
- Verify bot is actually a member (not just an admin with no read access)
- Check gateway logs: `journalctl --user -u clawdbot -f` (look for "skipping group message")
**Bot responds to mentions but not `/activation always`:**
- The `/activation` command updates session state but doesn't persist to config
- For persistent behavior, add group to `telegram.groups` with `requireMention: false`
**Commands like `/status` don't work:**
- Make sure your Telegram user ID is authorized (via pairing or `telegram.allowFrom`)
- Commands require authorization even in groups with `groupPolicy: "open"`
