Timeshift backup and grub btrfs

I am using timeshift autosnap and btrfs and grub btrfs
I am on endeavour os

Everything works fine
But when I update anything and reboot
This time snapshots are not visible in grub
But next reboot brings back those snapshots option

If any update broke my system
And I can’t find snapshots on grub
How can I boot into snapshots ?

Did you enable the service grub-btrfsd and install the package inotify-tools
