New-PSUVariable -Integrated error: The method or operation is not implemented

When attempting to create a variable:

New-PSUVariable -Name “Test” -Value “None” -Integrated

I receive the following error:

The method or operation is not implemented.

If I remove -Integrated and use -AppToken with a valid token, this works as expected. How can I create a new variable without having to use a token?

The command Remove-PSUVariable -Integrated works as expected.

Thanks
