At the moment I can snooze for me or for all the member of that team inbox.
The second option is not useful, because inside a team inbox there are observers too and, anyway, snoozing for everyone (members not assigned) creates just confusion.
I think that a good solution could be to be able snooze that conversation for the assignees.
Another option could be to archive the conversation not only for me (the person who snoozes), but even for the assignees.
