License server Activation - How to get the ProductID using powershell script

I wanted to partially automate the Activation of license server using the web browser method .

I wanted automate the below 2 steps using powershell script

1. Open RD Licensing Manager (licmgr.exe) on your server, right-click on the server name and choose Properties

2. Change Connection method to Web Browser, before closing the window write down your Product ID.

How do I write a powershell script which will display the Product ID to the user.

Thanks for the support
