Class not found for elFinder(Open-source file manager for web) in Codeigniter 4

Thanks you brother @nfaiz it's already solved by @paulbalandan on this post subject    but facing a new problem. I also test with your code but have a problem with upload image, all is ok such as directory listing, getFileCallback except upload image. In elFinder debug not show upload tab, In browser console show error with that connector link "Controller or its method is not found: \\App\\Controllers\\Filemanager::connector" but this controller file & function is unknown....
