Staying with some family this weekend for Thanksgiving, and they have DirectTV, so I was able to play a bit and get TV Provider login working in the container. Checkout the README for how to enable different events
This update also makes ESPN+ optional so you can use just your TV provider if you only have that. There might be some edge cases (I was only able to test 1 provider), but it was working fine for me as I've been testing it.
