FYI there is also “Island” (white triangles on blue yellow background) on the Google Play Store which does similar if you don’t want to bother with FDroid.

I use it for isolating work apps, only oddity is having to install a second instance of my favourite keyboard and browser app, and if I want to attach a photo to say Teams, the file picker will show nothing until you switch it to browse personal files.

As someone with waxy ears, an ear pick with a wifi camera built in. Would get blockages, cotton buds just pushed it back, olive oil or peroxide would get air locked. The webcam ear pick was super cheap and makes it easy to scoop out any lumps of wax.
