Wait, its installed by default? I assumed I had to install it, which would not be possible, because its immutable and there is no rsync flatpak (I think).

You can install system wide apps by turning off immutabe mode and configurating something. I might be talking out my ass though cause I have done this but I don’t remember if it persisted across updates.
