I believe most of these RCA projectors come equipped with a Roku Streaming Stick. The universal remote (if IR/infra-red based) won't be able to interact with the Roku Streaming Stick.
Will need to purchase a RF/wifi based remote like the Roku Voice Remote to control the Roku Streaming Stick. https://www.roku.com/products/accessories
If the RCA projector and the Streaming Stick have already been setup and activated, then you can also use the Roku Mobile app to control the Streaming Stick. (but will need to enable wifi so that the Stick and the app are on the same network). https://www.roku.com/mobile-app and https://support.roku.com/article/217288467.
