The official installation process won't work, as Bazzite is an immutable distro.
You can install it with rpm-ostree. If you choose to do so, I invite you to look into what immutable distros are, and what problems they solve (and create).
I was curious and searched if it was more complicated than it looked for ProtonVPN. It doesn't look complicated, but it is not very straightforward either.
You can find how to do it in the comment of this reddit post
It won't work. The app needs system-level access to work properly, which it won't have while running inside a container. The Flatpak works fine though.
You will need to export the app from the distrobox if I understand your problem correctly. I hope this is the correct link: https://distrobox.it/usage/distrobox-export/
From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
