Wanted to suggest an accessory (necessary for my app)

I wanted to suggest an accessory that would be necessary for one of the applications I plan on building. I don't believe this exists yet. I'm submitting to Meta because the devices are fair priced, and I'm pretty sure most will be getting the Quest 3, as opposed to other devices, and I want to ensure this accessory (if you choose to make it) will work without issue on the quest.

How/where should I make the suggestion?

I didn't want to do it on a public forum in case Meta wants to patent it.
