Using webdav storage as a file system on a immutable system - eviltoast

On immutable systems like bazzite, what’s the best way to mount webdav storage as a file system in order to open it with Cryptomator?

options i’m thinking are:

  1. use distrobox bc there i can install davfs and cryptomator
  2. look for flatpak softwares that enables this function

I’m basically clueless. Any kind of info would be much appreciated.
