Usage metrics over entire organziation

Hi,

in our organization we are trying to increase the usage of Power BI reports and dashboard with our users. We are working on ways to teach people how to use the reports and to create awareness the reports are available.

To measure our progress we made a dashboard based on certain audit logs.

Now we are looking for a way to find the users that have access to each report in the organization. This way we want to specifically target the reports that many people can access but few do.

Anybody know in which audit logs to search or another way to get this data?
