Telegram and Airplay, black frame.

Hi everyone, I'm reaching out you about an annoying Telegram setting that I can't seem to change.

In a nutshell if I play a video on Telegram and share the screen using AirPlay on my TV, it projects creating a big black frame along the edges, resizing the image and thus not full screen.

The only solution I have found is to zoom in from the phone on the video , which is then projected in 16:9 on the TV, but losing the actual contours of the image which at this point will be cut off by the zoom.

I use an IPhone 11 Pro Max.

Has anyone with the same problem been able to solve it?
