I have migrated my daughter's phone from Microsoft Launcher to Google Family Link. Everything works as expected (or even better) and the only problem (or actually one of two problems) we're facing is the irritating notification that Family Link displays:

How can I get rid of it?
I have tried to open the corresponding app (Google) notification settings. I found many entries there, but nothing that seems to be related to Family Link.
On one of two phones, I managed to resolve this by completely disabling the Google application from displaying any kind of notifications. But that's a workaround I'd like to avoid the most, if possible.
