The option to enable optic ID with a nearby iPhone is not showing up in my settings

I should be able to enable optic ID just by having my iPhone nearby , but this option does not show up under settings as this article instructs: Set a passcode and use Optic ID to unlock Apple Vision Pro - Soporte técnico de Apple. But this does not show up as an option in my Vision Pro settings at all. I watched someone else in youTube suggest to turn it on, but I don't have access to this feature. Can someone help?
