Sharing a project with owner-only connections

A project that read data through an owner-only connection (Gmail, Google Chat or a connection the company set up) can now be opened from the shared link: the collaborator sees who can open it and what to ask for instead of being stuck on Verify, without verifying their account.

In Share, the role that would reach that connection is locked with the reason and the path to the template; without outputs, the notice explains it with no button.
