As Teams administrator, you already well know the Dashboard being shown when logging on the Teams administration portal (https://admin.teams.microsoft.com/).
Well, you can now customize this Dashboard (same as for the Office 365 administration portal) to only display the information which are relevant to you.
To do so, connect to your Teams portal and click on the Edit option shown on the top right side of the Dashboard
As you probably still have the default Dashboard you will have the message “You have added all the cards to your dashboard”
You can then remove card(s) by opening the ellipsis menu (you know the 3 dots) and select Remove
If you have removed some card(s) they will be made available through the Edit option
