How to access hashtable returned from PowerShell

Help Studio
1

I have a PowerShell script that returns the following:

Collection(1)
{
Hashtable(5)
{

{
  "esn",
  "506C3KNQDRAA3YCX0061" 
},

{
  "agentStatus",
  "A" 
},

{
  "accountUid",
  "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx" 
},

{
  "deviceUid",
  "a33528ce-ba2e-40e6-9807-a36dd89a511b" 
},

{
  "isStolen",
  false 
}

}
}

How do I access the various values in Studio?
