How can one minimize Thunderbird to the tray bar in Debian 10/KDE?
Using bintray didn't work when trying to install it (sudo apt-get install birdtray) I get:
The following packages have unmet dependencies:
birdtray : Depends: thunderbird but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
I'm looking for other ways to get this done than using the Minimize On Close AddOn for Thunderbird because it requires the permission for "Have full, unrestricted access to Thunderbird, and your computer" and there might be other ways.
Various other AddOns don't run with the Thunderbird version that currently is in Debian's repos (78.11.0).
If there currently is no way to get this done, I'm also interested if there are any plans (issues) to build this functionality into Thunderbird so that it can be minimized to tray just like countless other apps that run on GNU/Linux.
