compatibility of meta neural band with Quest 3 and 4

Hello Meta team,

I would like to know if the Meta Neural Band works with the Meta Quest 3 and the upcoming Meta Quest 4.
I’m really interested in buying and testing the Ray-Ban Display glasses, but only if the Meta Neural Band is compatible with the Meta Quest.
I also saw on Kickstarter an amazing kit called “Fluxpose” that tracks full-body movements 
Does Meta plan to sell these accessories separately so that the Meta Quest price remains more accessible ?
