How to transmit at the same time the render of two or more different cameras?

HI, the need for my question is because I’m trying to find out how to transmit the render of different cameras at the same time on different platforms in real time.

For example within the scene I have 2 cameras pointing in different directions. The goal is to get the view from camera 1 to be streamed on instagram live and the view from camera 2 to be streamed on twitch.

please help with this.
