Is it possible to inform selected streams in a certain channel about the phantombot when they go live?

Look into the promote system. Currently only controlled by text command in Discord, use !promoteadm for setup commands. If you want members to be able to add themselves, they can use !promote for that setting. Also note that if members are adding themselves, they’ll need to have used the !account link setup to connect their Twitch and Discord.
