B2B Direct Connect + cross tenant access enables switch tenants functionality?

We have set up a b2b direct connect connection with another company. We have enabled the cross-tent sync settings.
We want to use Shared channels in Teams. This works fine.


It is now possible for the other company to switch tenants in Teams and log into our tenant and then they see the entire team and not just the shared channel. The can also access SharePoint sites.
Is this works as designed because I can't find this functionality in the Microsoft documentation.

    If you have enabled cross-tenant sync, those users are likely already synchronized to your tenant, so yes, this is the expected behavior. If you only want to use Shared channels/direct connect, cross-tenant sync is NOT a requirement.
