how to support "closed testing" for the track

[sk92129]

Hi,
How do I use this tool to publish to "Closed Testing" instead of "Internal Testing"?

It works for me when I use the default or :
play {
defaultToAppBundles = true
track = "internal" // 'alpha', 'beta', 'rollout' or 'production'
// it isnt clear what the format should be for this serviceAccess.json and how to protect content
serviceAccountCredentials = file("serviceAccess.json")
//resolutionStrategy.set(ResolutionStrategy.AUTO)
}
But if I changed the track to "closed", "closed testing", i get an error.

 {
   "code": 400,
   "errors": [
     {
       "domain": "global",
       "message": "Track not found: closed",
       "reason": "badRequest"
     }
   ],
   "message": "Track not found: closed",
   "status": "INVALID_ARGUMENT"
 }

I see anything here mention about closed testing. But i found another approach by uploading to internal and promoting manually to closed testing

Oops, thought you meant "Internal app sharing."

alpha should go to the play console "Closed testing" section.
