automatically loading grubaa64.efi from UEFI in arch linux arm

Hi
I've installed arch linux arm.
But it's not booting the .efi file automatically in UEFI.
to boot at the moment I manually search the .efi file and enter it.
My question is, how can I make arch linux automatically do it.
I would also want to understand how UEFI automatically loads the .efi file in UTM and in general.

I wrote this for debian:
https://github.com/utmapp/UTM/issues/4002
So I tried making /boot directory and copying the grubaa64.efi and grub.cfg to there. It didn't work.
I also tried this:
https://github.com/utmapp/UTM/issues/2503
but it didn't work.
This worked in the first time I booted arch but then it stopped.

Please help.
Thanks in advance
