Add-PWUserstoConnectedProject Project Roles


I've found that Add-PWUserstoConnectedProject adds users to PWDM. Is there a way to only add users to the PW Project and not PWDM?

Is there a way to also assign project roles (not PWDM roles - issue/receive/review)?

I've tried this cmdlet with one user and they haven't received the Bentley invite email. Should the email still send?
