This allows individual participants to retain the same unique ID that can be referenced for the duration of the video call, even after a dropout. Similarly, otherParticipantCount is not decreased when a participant leaves. However, if the the video call ends then the participant array and count are both reset.

Importing this module automatically enables the Participants capability within the project's Properties.
