Show new email notifications in Teams

Hi

I'm trying to show a Teams notification for all new email sent to an M365 Group/Team. This is relatively easy for a distribution list, just add a contact with the channel email address as a member. But it doesn't work to add a contact to the group/team.

What is the preferred way to achieve this? I thought this would be easy, but apparently it's assumed that everyone adds the group mailbox to Outlook to get notifications.
