Custom Streaming and Powerpoint Live

Hi,

I'm trying to use Teams to stream our meetings to YouTube and would love to be able to do that to include Powerpoint presentations using Powerpoint Live.

I've found that if we share a screen, the content is shown on the YouTube stream, but if a user presents through Powerpoint Live - the content never makes it onto the stream.  Are others having the same problem, and has anyone found a way around it please?

Many thanks
