JMESPath --query filter for an unusual array (dictionary), anyone up for a challenge?

Question

As you can see the picture below. I want to filter descriptor value where subjectkind is group. The azure CLI command I am using to get the descriptor is

az devops security group membership list --id $var1 --org https://dev.azure.com/$OrgName/ --query "*.descriptor" --output tsv

It gives me the output but I am not able to filter the output based on the condition in the JMESPath query to get get the desired output.

FYI: I am using Windows PowerShell ISE

This is not a normal array of dictionary, here you can see the sub properties have same Key value pairs but the top node is different.

C:\Windows\system32> az devops security group membership list --id $var1 --org https://dev.azure.com/$OrgName/

    enter code here
{
  "aad.MDQwNjg0MDMtOWYwOC03OTM": {

In order to filter on a dictionary, you can use an object projection, with *.
With this you are coming back to an array, that you can further filter when the first projection has been stopped, with a pipe expression.

This gives you the query:

* | [?subjectkind == 'group'].descriptor

That, on this example JSON:

{
  "aad.some_gibberish_characters_group_1": {
    "descriptor": "aad.some_gibberish_characters_group_1",
    "subjectkind": "group"
  },
  "aad.some_gibberish_characters_user_1": {
    "descriptor": "aad.some_gibberish_characters_user_1",
    "subjectkind": "user"
  },
  "aad.some_gibberish_characters_group_2": {
    "descriptor": "aad.some_gibberish_characters_group_2",
    "subjectkind": "group"
  }
}

Would yield:

[
  "aad.some_gibberish_characters_group_1",
  "aad.some_gibberish_characters_group_2"
]
