Is there an app or chatbot that serves like a regular attendee in the meeting. If anyone send a message in the chat (either directly to the chatbot or to all attendees), the message should show up on a centralized dashboard. And maybe a team member on call can respond promptly on the dashboard, and the response will appear in their chat.
One popular option is Microsoft Teams, which has bots and integrations that can handle and display meeting messages on a dashboard. Another option is Slack, which can gather and display messages centrally with the help of bots like Standuply or Geekbot. You can also look into Zoom with integrations like Zoom Chatbot to manage meeting interactions.
