Telegram App hacking mic/camera?

Over the last couple days, I noticed some very strange activity whenever I was on Telegram.

A couple days ago I was scrolling telegram, and I noticed that the orange light came on on my phone, indicating that my mic was on.

And then, yesterday, I was on telegram and everything looked normal, but then I moved my hand in such motion that it covered the camera and the Telegram screen went black. It took me a few times and moving my hand back-and-forth to figure out what was actually going on. Every time I covered the front facing camera with my hand, the Telegram screen went black immediately.

That would indicate that the proximity sensor is being triggered. Does telegram allow you to make voice calls?
