CHM files do not open

[HananKrishna]

According to the Flathub page for Okular, the program should be capable of running CHM files. But instead I see the following error message pop-up on my screen inside the Okular window.

Could not open file:///var/home/user/Downloads/file.chm. 
Can not find a plugin which is able to handle the document being passed.

This is on Okular 24.08.1
OS is Fedora Linux 40 Kinoite.

Is there any possible way I can try fixing this, or is CHM support dropped from Okular?

According to buildlog CHM support should be enabled:

...
 * LibZip, A library for reading, creating, and modifying zip archives, <https://libzip.org/>
   Support CHM files in okular. You can make the dependency optional adding LibZip to the FORCE_NOT_REQUIRED_DEPENDENCIES cmake option
...

It's interesting that opening CBR files also stopped working.

I see there is discussion regarding CBR in issue #331. There is also a pull request #368 that unsuccessfully tries to resolve this.

Is this a problem related to libzip or is it still an issue with the Okular flatpak?

Okular does not support CHM files anymore unfortunately

Would the following merge req at KDE be best to note as confirmation on CHM henceforth being unsupported on Okular?

Why do you need more confirmation than my confirmation?

For reference if anyone else comes around searching for it.
Having multiple spaces on the internet pointing to the code-source that states this change is a good idea as a form of redundant clarity.
