GRUB Theme not installling even after Finding theme correctly on Fedora37

[AviVarma]

The Issue

After modifying my /etc/default/grub and installing using all of these commands:

sudo grub2-mkconfig -o /etc/grub2-efi.cfg sudo grub2-mkconfig -o /etc/grub2.cfg sudo grub2-mkconfig -o /boot/grub2/grub.cfg

I haven't been able to install the theme, I'm getting the default black and grey grub menu.

My /etc/default/grub
