Is the AppImage install for Ubuntu meant to be standalone?



I’m trying to get Cryptomator working and I really like what I see.

I am using a fork of Ubuntu (called POP! OS from System76).

Anyways - when I tried to install the software via the terminal install I got an error which was the “cryptomator not found” which I assume relates to this previous forum post.

So, I followed the route of the AppImage which works great - but - it appears that I have to “install” the programme each time or am I mistaken on how an AppImage works? Is the Cryptomator AppImage meant to be executed each time on my machine, i.e. it is not meant to be hard installed?
