Clone Flatpak to other users?

Is there an easy way to import or clone a users flatpak program to another user? I know the easy way might be to just install to every user.
Single system, not any sort of remote.

what’s the motivation for this

Not sure I needed to have a motivation.

I use one user for one environment and other for another. The networking is completely different. Too much trouble to edit them.

Either I need to start installing flatpaks for all users or I need to clone a fully installed user or I need to use command line flatpak options to save and offline install to the other user.

Naturally I would think how to solve this instead of “cloning” flatpak applications, which is just not what meant to be done.

Just for reference I see that gnome-software can have an option to flatpak system or per user.
