Whatever protocol you are using, if there’s enough participants, one person can decide to take the role of the Lurking Listener.
The Lurking Listener doesn’t actively participate in the conversation, they take a peripheral position. Their task is to actively listen to the dynamics in the group, to put out feelers and note down keywords, changing tones, silences and moods.
They can note it down with words or lines or drawings, as it comes.
At the end they share what they noticed and talk about it with the group.
If possible with the software you are using, it’s good practice to hide Self View in order to focus on others rather than on one’s own image.
