Mute or silent specific participants

Hi , i am working with openVidu to implement a translation conference feature that allows more than one participant to speak at the same time (translators), in the other hand there are other participants everyone is interested in a specific language (one translator), so what I am trying to do is mute all non-translators participant and also mute/silent other translators for participant who want to listen to the specific language.
so how can I achieve that and if there any resources that can help me out.
Thanks
