EFI partition seems not synced on proxmox installed on btrfs raid 1

[Fantu]

Hi, I did a new installation of proxmox, using installer of latest version iso (proxmox-ve_8.2-2) and installed on btrfs raid 1.
During the first update of the system packages I noticed this at the end:

...
update-initramfs: Generating /boot/initrd.img-6.8.12-2-pve
Running hook script 'zz-proxmox-boot'..
Re-executing '/etc/kernel/postinst.d/zz-proxmox-boot' in new private mount namespace..
No /etc/kernel/proxmox-boot-uuids found, skipping ESP sync.

FWIK proxmox boot tool should keep synced EFI partition when using zfs or btrfs raid, but it seems don't setted correctly by installer

proxmox-boot-tool status
Re-executing '/usr/sbin/proxmox-boot-tool' in new private mount namespace..
E: /etc/kernel/proxmox-boot-uuids does not exist.

EFI partition are they actually out of sync in btrfs installations or is there something else I don't know about that syncs them?
Thanks for any reply and sorry for my bad english.

I tried another search, but I didn't find certain information if the installer does not automatically set to synchronize the EFI partitions of the system raids it creates.
I found some topic on zfs raid disk replacement where proxmox-boot-tool should be used on the new disk.
For execute on btrfs raid1 of clean install I should do on both disks EFI partition or only the second one not mounted (/dev/sdb2)?
man of proxmox-boot-tool is missed and --help only list arguments without details, based on https://pve.proxmox.com/wiki/Host_Bootloader the procedure seems this:

proxmox-boot-tool format /dev/sdb2
proxmox-boot-tool init /dev/sdb2 grub

but still not sure if I should do this or not and only to second disk or both.

Thanks for any reply

Today I tried a test installation with raid1 zfs and /boot/efi is keeped not mounted but with proxmox-boot-tool the 2 EFI partition result (so should sync them when needed):

proxmox-boot-tool status
Re-executing '/usr/sbin/proxmox-boot-tool' in new private mount namespace..
System currently booted with uefi
E69A-A3E9 is configured with: grub (versions: 6.8.4-2-pve)
E69B-92C9 is configured with: grub (versions: 6.8.4-2-pve)

Why installer don't do the same with btrfs, do something different or is simply missed to implement this part (related to btrfs) in the installer?
