Mute option / Quiet mode for ChatGPT Voice Chat

I spotted the fact that it is not possible to mute / disable sound effects (received a response from a user / processing it / thinking on the response to the user / the answer itself) during a voice conversation.

I think it would be a nice feature to implement, my use case is - I create a custom ChatGPT agent that sends responses to a separate endpoint, I want to manage it with voice but receive the results visually, there is no option to disable voice sounds / answering.
