Hi @P_Paul,
Before you utilize the Power Apps cmdlets, execute these commands:
Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Force
dir . | Unblock-File
This should help with the error message above. After, you will want to install and import the necessary modules:
Install-Module -Name Microsoft.PowerApps.Administration.PowerShell Install-Module -Name Microsoft.PowerApps.PowerShell -AllowClobber
In terms of the linked New-FlowOverview PS module, it's third party so if you have issues with that, you will probably need to reach out to the Module owners.
You may want to take a look into the Power Automate Management Connector, which allows you to list Flows as Admins: https://docs.microsoft.com/en-us/connectors/flowmanagement/#actions. 😊
Thanks!
