What is the difference between the Volume Content section of Jamf Pro vs the Mobile Device Apps section of Jamf Pro?

The Search Volume Content section shows the applications listed in Jamf Pro, which Volume Purchasing location the content is coming from, how many licenses are available and in use, and the content type.

The Mobile Device Apps section and Mac Apps > App Store also show which applications are listed in Jamf Pro and associated with the Volume Purchasing locations but it will allow us to distribute the applications to the devices within this section.
