how to replace the fixed square icon with a hashtag icon ? I want the hashtag icon to appear fixed [The image shows a menu with various categories such as Documentation, Support, Community Wiki, and more. (Captioned by AI)]

this does not apply to subforums, only to main threads

They work on subcategories too, at least in my case.

איך משנים את איקון כותרת הקטגוריה?
