Where do I see the Telegram groups and channels I am in?
Open Settings → Organizer tools → External communities to see every Telegram group and channel you share with the Playbox bot. Each card shows whether it is a group or a channel, your role there (admin or member), and the member count.
Tap a community to open it and jump straight into the chat in Telegram. If you are an admin, the same screen also gives you its settings, so members see the list without controls they cannot use.
The list fills itself from Telegram: a community appears once the Playbox bot is in it and drops off when the bot is removed. To add a new one, use Add the bot to a group or channel at the bottom of the screen.
