(Linux) pressing the play button doesn't seem to have a handler configured

[xana43]

I just transitioned to Fedora KDE from windows 11 so I'm not sure how much of this is user error.

I reinstalled Beat saber and ran it once so that all the default configurations are present. When I go to use
the mod manager and tried to click on play it didn't seem to do anything. So I opened it up using the console and whenever I click play I get this error

It seems like your OS doesn't yet know what to do with links to Steam (e.g. steam://run/730 for launching Counter-Strike 2).

Alternatively, you can test if it works also by running xdg-mime query default "x-scheme-handler/steam" in a terminal window.

If it doesn't say steam.desktop as a response to the previous command, then the way to fix it is:

1. Locate your steam.desktop file (kind of like a shortcut to an app).
2. Open it with a text editor (e.g. kate).
3. Make sure it has the line MimeType=x-scheme-handler/steam; somewhere in it.
