A new widget to manage the current web app from the app browser

[bam80]

Description

Since we installed the PWA, it should be self-contained as possible and don't require opening "Big Brother" browser for it's operation.
Particularly, it should be possible to delete the app from it's own window.
Right now it's not possible, or I didn't find how.

Additional Information

I will probably make a custom widget for managing the current web app (editing and uninstalling) from the app browser in the future. However, I don't have much time currently so I don't know when it will be ready.
