SPFX extension does not load on Site Contents page

Question

I've developed a CSS injector application customizers that loads the.css file from the style library and applies it to the website. However, I discovered that the extension is not loaded when users are viewing the Site Contents page.

Is there a way to load the extension on the site content page?
