Hello, I installed Calibre on Fedora via flatpak but I need to use this command, at least for the first time when running caliber:

flatpak --socket=system-bus --device=all --filesystem=/run/media/leslie/Kindle run com.calibre_ebook.calibre

Otherwise my Kindle is unable to connect to Caliber. Does anyone what does the command above specifically do in plain English? Does it open the system bus or something?
