I've tried that already, doesn't make a difference unfortunately.
When going to https://www.fab.com/channels/ for example which results in a page not found page, the button is shown top left. for other pages with channels or search in the path, it doesn't. it seems like the wildcards don't work.

Found out some more, the script gets loaded fine, it's just that the button doesn't get shown on top of Epic's UI. What could I try to fix it?

Try clicking this URL:

The script works fine on my browser，check the screenshot
