I tried this but as you can see it defaults to emacs for some reason on my system:
xdg-mime default bower.desktop 'x-scheme-handler/mailto'
xdg-mime query default 'x-scheme-handler/mailto'
emacs-mail.desktop
Have you ever needed to set this up on your system for bower?
My use case is clicking on the "reply to thread" link here: https://lists.sr.ht/~whereiseveryone/guixrus/patches/32491
It currently opens in emacs (by default it was opening in protonmail web client ;()).
I'd like to be able to click on the link and it open in bower to reply...
