OK I've enabled the SAS API in my Google Could Compute How do I put my CPIRD and certificates in?

I have done the above steps and have signed up for support. Am I able to use both Google and Federated Wireless as a SAS vendor ?

If I have a Federated Wireless account. how do I transition that CPI certificate to Google SAS ? I have Telrad CBRS equipment and would like to switch providers.
