Ujust regenerate-grub error: Justfile does not contain recipe `regenerate-grub`

Where did the entry to regenerate grub went? I wanted to remove an old zombie entry of Windows Boot manager, and have the new one detected, as the new Windows EFI is on another disk. I can’t find any other way to remove/regenerate this.

Seems to me it’s currently only available in Bazzite. Perhaps it was removed from Aurora due to dual-booting being unsupported, but I’m not sure.
