Compatibility issues with Gnome 47.2 and newer

[FlammLex]

Hello,
I love CustomOSD!

The problem is that I am using Gnome 47. At first, by adding "47" to the metadata.json, I didn’t have major issues.
But since version 47.2, it no longer works properly and keeps crashing.
Unfortunately, I don’t know much about programming, so I can’t fix it myself.
I would be very grateful if the extension could be updated to support Gnome 47 and 48.
I would really hate to have to stop using this extension.
Thank you very much for the great work!
