 ## Role assignment changes 
-Organizers, coorganizers, and presenters can promote and demote participants during the meeting. This role change can lead to the loss or gain of new functionality. Developers can subscribe to the `roleChanged` event of the `Call` object to update the user interface based on the role.

Developers can read meeting options before the meeting starts with [Graph API for `onlineMeeting` resource](/graph/api/onlinemeeting-get). As developers currently don't have a way to read changes during the meeting, we recommend limiting the changes during the meeting to ensure the best user experience.
