This got confirmed on the Mania kickoff thing to debut on Twitter/X in the spring of this year.
Honestly, probably not something i'm going to be taking an interest in but it does some like a good concept for what they want to do with it.

I honestly wouldn't be surprised if it was never seen on TV, purely on social media.
