Having issues casting from my iPhone 13 Pro Max to my android based SmartTV

So i’m up-to-date regarding my software and up-to-date regards to the firmware and everything is up-to-date. I just don’t know why it’s not even trying to be problematic however I’m not even seeing where I would even go in order to try to reinstall these TV settings but I’ve done research for about three days now and I can’t figure it out so I’m hoping that there is somebody out there that can and will be knowledgeable in regards to what I’m saying and if so, please let me know greatly appreciate it thanks
