This technique is doomed to failure. debian-10.7.0-amd64-xfce-CD-1.iso
needs to be mounted when it is found. However, the installer's initrd
does not contain a loop module, so this is not possible.

David Wright's advice to use the hd-media kernel and initrd is your way
forward. The simplest GRUB stanza possible is

   menuentry 'Debian 10' {
   linux /boot/vmlinuz
   initrd /boot/initrd.gz
   }
