The text discusses the concept of meeting owners and admins in a video call context. Meeting owners have special privileges to manage room access, such as sharing media, starting or stopping live streams, and updating other participants. Admins are similar to owners but can be demoted and have more granular permissions. The text then focuses on sample code that demonstrates how to let meeting owners promote regular participants to admins or remove them from the call using Daily's Client SDK for JavaScript. It explains how the `updateParticipant` method is used with the `canAdmin` property to share admin privileges and how to eject a participant from the call using the `eject` property. The code uses Next.js and Daily Prebuilt, and it updates the UI when participants are promoted or removed from the call.
