The corporate content system leverages the users and groups in your org. You have to assign the application to them, and the respective users must be logged into their org-linked accounts in the headsets.
In the corporate content list view, the 'Add New Content' button at the top right will change to 'Delete Content' and 'Assign Content' when you have one or more applications selected by checkbox.
In the individual app page, on the left side of the pane you will see 'Content Detail', which is the default view. Switch to 'Assigned User" below it to modify assignments for that particular app.
