I turn off/no to push notifications on every app that has ever asked for it, except Messaging and Calendar. Nothing else I've ever installed has warranted more than a little red notification dot on the icon.
Why cannot it be automatically "no" for all push notifications? A website should not even be allowed to ask me.
MS Teams already gives me a lot of push notifications during my work day, and if the browsers starts to do this, I will be overwhelmed with beeping nag-notifications.
Computer clutter is a distraction and lowers productivity.
IIRC by default Firefox doesn't prompt you when sites request to send you notifications. But it's possible, i just set some configuration a long time ago and forgot about it
This is the way. In addition to those, I have a silent e-mail count badge for Gmail and WSJ news alerts (because they are tangentially relevant for my job)
