How to merge multiple GoPro streams and bring them to YouTube?

Question

YouTube

Hello!

Given:
• 3-5 GoPro Black 7 cameras, with an internet connection and the ability to conduct live broadcast singly.
• Viewer in Youtube (more than 1k subscribers -> there are no restrictions on streams from youtube)

Need:
Combine streams from cameras into one, so that the browser can broadcast and comment on video broadcasts from several cameras live. Video layout grid or switchable (would be ideal). Comment in a voice louder than from the cameras - so you also need to have control of the sound from the streams from the cameras. It is done to review active team sports, where the whole team will have cameras on their helmets. It would also be nice if the reviewer himself was visible.

I would be grateful if you tell me which software to look for or if there are any other solutions.
