Plugin assets and .xsl file

Hi, according to the documentation, files in plugin assets folders are accessible through media folder.
It works fine with .js and .css, but not with .xsl file. It looks like there is a file extention filter somewhere.
/site folder is blocked by .htacces, and for security I don’t want to change this behavior.
Is there a way to solve that problem ?
Thanks

See the discussion here: Kirby has opinions on what a plugin asset should be · Issue #5247 · getkirby/kirby · GitHub

Thank you. As I understand, it will be fixed in 3.9.6 ? So I can apply the patch now ?

Not sure from the discussion.
