Access the Tuner for Broadcast TV stream

I have been experimenting with various Tizen Project templates trying to figure out if i can build an application that display the Channels available to users through the Live TV widget on the home screen. I’d like to overlay some custom content at certain times over the top of these broadcast channels. CHAT GPT tells me that Access to the tuner is impossible, is that correct ?? I have a modern 2023 Samsung 65 inch TV .
