Gnome custom cursor not working in all applications.

Hey all. Basic information I am running Pop_os! I have have downloaded and placed a cursor in ~/.icons folder and selected it with gnome tweaks. It seems to work on some but not all applications. It works on Steam, gedit, nautilus but not on any browser, Telegram, or Thunderbird.

I have tried modifying the /usr/share/icons/default/index.theme file to my selected cursor. I have restarted and no changes.

To note: Gnome Tweaks still lists Adwaita (default) no mater what I do.

Is there a way for me to get my chosen cursor to work with all applications?
