Tails 6.14.1 changes - flatpak is installed in the OS

As of Tails 6.14.1, flatpak is already installed. The Tor Browser uses.

For Signal-Desktop setup, this means

• sudo sed -i '$ a /home/amnesia/.local/share/flatpak source=flatpak\n/home/amnesia/.var/app source=var_app\n/home/amnesia/.local/share/applications source=applications' /live/persistence/TailsData_unlocked/persistence.conf This will work, but it will also persist some Tor Browser cache files which would be harmful towards users.
• I think torsocks flatpak install -y flathub org.signal.Signal should have been torsocks flatpak install --user -y flathub org.signal.Signal
• Enter this line in the terminal and press Enter to make the Desktop launcher available (it will not use the Signal Desktop icon but a generic one) It does now use the Signal Desktop icon.
• The desktop files for updating flatpak apps needs --user

Maybe instead it should be changed to use the Signal APT repository? https://tails.net/doc/persistent_storage/additional_software/index.en.html#index7h1
