Set Teams as default app for tel: using PowerShell script.

Hi,

I want to set Teams as default for tel: protocol using PowerShell script.

I have used the following command to get the current app:

(Get-ItemProperty 'HKCU:\Software\Microsoft\Windows\Shell\Associations\UrlAssociations\tel\UserChoice' -Name ProgId).ProgID

the result is 

ChromeHTML

When I tried to use Set-ItemProperty using TeamsURL as program id, it is not working, the default app was reset to empty.

Set-ItemProperty 'HKCU:\Software\Microsoft\Windows\Shell\Associations\UrlAssociations\tel\UserChoice' -name ProgId TeamsURL

Any help would be appreciated.

Thanks
