Do we have anything in Roku similar to TestFlight in iOS and rollout-to-internal testers in Android?

Do we have anything in Roku similar to TestFlight in iOS and rollout-to-internal testers in Android?

Can I submit and release the Roku TV app/ channel to list of internal testers only to test. Once the feedback is positive. The build will be submitted for review and released to public.

You can send out a link to allow people to install an unpublished channel

There’s nothing to restrict who can use it though, as far as I know.
