Hi@Marty_Dub,
Based on the issue that you mentioned, do you want to get all the users who are assigned to an app?
Could you please share a bit more about the scenario?
Actually, PowerShell does have an available command you can use to get a list of Power Apps app owners and users.
Get-PowerAppRoleAssignment -AppName "AppID of PowerApp"
Since you do not have access to it, just ignore this.
If you want to get a list of Power Apps app owners and users in Power Apps, I am afraid that there is no direct way to achieve this currently.
Here is a similar idea you can vote for:
Ability to export shared users name - Power Platform Community (microsoft.com)
As an alternative solution, you could get a list of shared user here:
(choose an app -> choose ...->choose Share)
Hope it could help you.
Regards,
Qi
