Viva Engage Community Notifications

I think if you make it a private community instead of public, then only members who've joined it will get the update (then they can opt out of email notifications if they don't want it, or pick which communities they want to receive notifications from). So if different departments had their own community, they just keep it private to them and no one else would receive an email.

My bigger issue, which I can't find an answer to anywhere is how we can get notifications in Teams, instead of an email, like the normal Teams activity feed bell notifications.
