To do so, select Telegram Group in the Add Resource menu (@InviteMemberBot > /myprojects > your project > Channels and groups > Add resource):
Select Telegram Group: Create your private Telegram Group or press the Connect Group button and create it later.
Choose your group, or make one if you don’t have one. Click “Create a New Group for This” if you haven’t made a group yet.
Press "Send" to confirm.
You'll then be prompted to connect your Group to any existing subscription plans, or create a new one.
Once finished, your group is connected now!
