Exactly, since you’re on Teams Personal / Communities, you don’t actually have a Microsoft 365 groupId.
So when someone asks you for your “MS Teams ID,” you have two options depending on what they mean:
If they want to join your community
Share the community invite link:
https://teams.live.com/l/community/FEAXS1YuDJG2...
That is your community’s “ID” in Teams Personal, and the only way others can join.
If they just want to connect with you on Teams
Share your Microsoft account email address (the one you log into Teams with).
That’s your “Teams identity.”
They can search for you in Teams or add you as a contact.
