Manjaro - Missing Boot Entry from UEFI

After unplugging my NVme SSD from my computer to test another OS. My manjaro installation disappeared from the boot menu.

After reading how Arch initializes under UEFI. I have mounted the ESP partition in my disk.

And copied the EFI/GRUB/grubx64.efi to EFI/BOOT/BOOTx64.EFI as suggested in the Arch Documentation.

EFI/
├── BOOT
│   └── BOOTx64.EFI
└── GRUB
    └── grubx64.efi

2 directories, 2 files

It fixed the issue and the UEFI entry reapered in my boot options screen.
