Starting Cryptomator in background (OpenSUSE)

Hello!

I want to start Cryptomator as a background app (in systemtray if possible) and open a vault without popping out a GUI (this can be easily done by the cryptomator by default).

My objective is to boot my pc and automatically open the vault so my auto-start apps can have access to the encrypted data.

There is a way to do that or it’s completly impossible?

Thank you!

EDIT:
I already tried with the “–background” parameter using flatpak but it just stats Cryptomator as default.
