Plan Usage API

I am trying to use the “Get Plan Usage” API to get the Zoom Plan utilization in my organization. 

https://developers.zoom.us/docs/api/rest/reference/billing/ma/#operation/GetPlanUsage

However the “type” returned by the API is not available in the plan list that zoom has published here. This is making it difficult for us to deduce the plan name.

Ex: "pro_zvu_monthly" is returned in the API response. But not available here:
