In your cloud video control room, the autoswitch and automute functions can be activated here:

The autoswitch function automatically brings the person speaking to the foreground. In the case of a provision as below, the autoswitch will automatically switch over the person speaking in large numbers.

The automute function automatically mutes the microphone of all speakers, except that of the main speaker. This function is to be used, for example, when only one person needs to speak at a time without being disturbed by outside noise.
