grub-btrfs, btrfs subvolume snapshots in GRUB boot options

hello guys, does anyone know how i can include btrfs snapshots in GRUB boot options? I usually use grub-customizer to add or edit boot entires.
Grub customizer has various options to add boot entries like  Scripts,Linux,Linux-ISO,Chainloader,Memtest and other..
I guess i can add an entry with grub-customizer, i am not sure on how to do it tho
Thank you

Maybe install openSUSE in a VM, minimal system is OK, find your way to yast and install something (anything). That'll cause some snapshots to be taken. And then when you reboot there should be a GRUB submenu from which to choose read only snapshots. From that state, you can maybe try to reverse engineer how it works. I know the openSUSE patches for GRUB to find snapshots is upstream for a while now, so it should be possible on Arch.
