Roku/TCL airplay

So, I did not know that you could airplay for a TV like this. So I noticed that I could connect it as a HomeKit accessory. So, naturally I tried to do this, but with no avail. I scanned the code presented on my TV, and so my phone started to try to connect, but it was not successful. I tried to enter the code manually, and the same results appeared. What am I doing wrong? The TV is connected to the internet, my phone is connected to the internet and on the latest version? I kept my phone on the mantle literally right next to the TV, and made sure the screen did not turn off! I just want to know if there is anything I can do to make it work? Obviously, in the photo I am not near the TV, but I was not trying to pair it...
