Integrate two tenants for education purpose.
Getting the guest access to be able to:
1-Create a Team
2-Create private channel in existing Team.
3-Adding members in private channels and Teams.
As in education tenant, external professors are always requested to give lectures using their own accounts located in other tenant.

The fact in there, that is, with Teams, we can't be anymore using SSO, and we must create multiple login in different tenants... 20 years back!
