Audit Power BI App user list

Hi lbendlin , it's a mixed. I'm using audience feature for some of the apps. and yes my audiences includes distribution lists. 

say I have published two apps, one called `sales` App and one called `client` app. for the client app, I'm using the audience feature and for the `sales` App, I'm not using audience feature. 

What will be the best way to find out the list of users to those two apps? It's okay to stay at the distribution list level without going into the distribution list and find out each individual within the distribution list, I did write a powershell script to pull the individuals from the distribution list. Thank you!
