If you would like to add media widgets to the reports, here's a quick overview of how to achieve it:
​
​

​Step 1: The first thing to note is that there are two options of media widgets. You can choose the Compact Media and the Expanded Media widget. Choose which one you want in the "Build your own" section or just drop one from the Pre-made widgets if it's available.

Step 2: Select your metrics, dimensions, and whatever necessary information you need. Furthermore, if you want the widget to be scrollable, enable it in the widget "Settings" section.
