Here are the notifications you should get by default
Chat—when someone sends you a message in a one-on-one or group chat.
Mentions—when you or a channel you're a member of is @mentioned.
Replies—when someone replies to your post in a channel, or to one that you've also replied to.
Calls—when someone calls you via Teams.
Meeting started—when someone joins a Teams meeting on your calendar.

Here’s a fix for it
Getting some notifications but not others
Your Notifications might be customized.
If you’re only getting alerts about certain kinds of activity, some notifications might be turned off.
Go to your profile picture at the top left of the app and select Notifications. Tap General activity and turn on the toggle next to any notifications you want to receive.
Getting zero notifications on your mobile device
Teams notifications might be disabled.
There are two ways to fix notifications on your mobile device: one is through settings in Teams, the other is to go to the Settings app on your mobile device.
We ask for permission when you first launch the app, but you may have skipped this step, or turned off notifications from the device’s Settings app.
Here’s what to do:
In Teams, go to your profile picture at the top left, then select Notifications.
If your notifications are turned off, tap Open settings.
From the Settings app on your mobile device, select Notifications.
Toggle on Allow Notifications.
