A flow connector that can remove the chat/chat group from Microsoft Teams after the event ended or at a defined interval. Since there is no feature of generating Join meeting link from the flow. A workaround was to use a pool of generated links and add them in the event invite. However, this keeps notifying users who are not in that day's event.
Alternatively, an option to remove chat for all the optional participants should also do. In this way, these users can be added in optional section and flow can remove them from chat once the event ended or at a scheduled duration.
