Roblox studio will not pick up on any new wireless controllers while open.
Connect a wireless Xbox controller while you are in Roblox stuido, then click Play Solo

You need to publish whatever you’re working on, close studio and then reopen it in order to register any new Xbox controllers.
This takes a while to do and is a big annoyance with slower connections when you’re just trying to quickly test an Xbox feature
