I can’t get my airplay to work on my Samsung TV

Samsung H6350 Series is a 2014 model, and doesn’t support AirPlay itself. (No model before 2018 had that.) To bring Apple AirPlay capability to the TV, you will need to connect an external Apple TV set-top box or other compatible device.

If you have that, then please specify which model. Identify your Apple TV model - Apple Support

… but the Samsung tv is an Apple TV

That seems contradictory. Can you explain?

Does you TV support Airplay 2 (Airplay 1 won't do for videos)? Please provide your Samsung TV model so that contributors can check its compatibility. Or you can check directly on the Samsung website.

I'm sorry but I don't own an Samsung TV but there seems to be several sources on the internet that can help you, starting with with video: https://www.youtube.com/watch?v=CgeiLnd5yz4
