Bazzite/any immutable distro question: every user duplicates app installs

Just installed Bazzite and it seems to work well so far.

Then I added a second standard user to the system and thought they'd have access to all software I just installed for the main user.
But that doesn't seem the case, Bazzite prompted me to install all those again for the second user.

Is that just a thing with immutable distros or did I do this in a wrong way? I tried looking this question up, but I couldn't find any info on multi user setups with immutable distros.
