Most channels connect with a one-click authorization:
- Channels → Add channel → choose the platform.
- Approve the requested permissions on that platform.
- The channel returns to your list, connected.
A few platforms work a little differently:
- Bluesky uses your handle plus an app password (created in your Bluesky settings).
- Telegram uses a bot token from @BotFather plus your chat ID.
- Discord posts through a bot added to your server.
If a connection fails, try again and make sure you grant all requested permissions — partial permissions can break publishing.
