**Describe the solution you'd like**

Currently we only show Videos and Images. It would be nice to have an alternative view where the media is grouped by item instead, so you just have to scroll down as the meeting progresses and have the next media ready.

**Additional context**

Start by locating the Media package and, if needed, the Core package for metadata, then inspect how videos and images are currently represented. Define the alternative item-grouped result so media can be followed in meeting order, and verify that the API exposes the next media as the meeting progresses.
