Connect to tv

I have Samsung S7 and Samsung Smart TV.

I can transfer and see/hear TV on the phone. I can do the opposite and view/hear videos and audio files on the phone via the TV.

However I have been unable to send xiia live stream to listen via TV speakers. When I click share --> bluetooth the TV is not visible (but the carea bluetooth strangely is).

If bluetooth is already connected (phone to TV) is it possible that is the reason the TV is excluded from the xiaa bluetooth share list of devices. Any advice what I can try next greatly appreciated.
