How to get a list of groups where the user is an administrator?

Question

API

Do I understand correctly that this requires the group.getUserGroupsV2 method?
But how can I find out where I am an administrator among this:

{
  groups:[
    {
      groupId:5523914...0280
      userId:5620...83752
    }
    {
      groupId:53038...6008
      userId:5620...83752
    }
    {
      groupId:55212616...440
      userId:5620...83752
    }
    {
      groupId:505821....315
      userId:5620...83752
    }
    {
      groupId:527762...2173
      userId:5620...83752
    }
    {
      groupId:47369...62535
      userId:5620...83752
    }
    {
      groupId:513161...378191
      userId:5620...83752
    }
    {
      groupId:527482...53549
      userId:5620...83752
    }
    {
      groupId:51565...407545
      userId:5620...83752
    }
    {
      groupId:468390...299047
      userId:5620...83752
    }
  ]
  anchor:LTE4OTI2Mzc0NzQ6LTE4OTI2Mzc1MTA=
}

In the response example on the method page, there is also a role field in the group objects. Why is this field not being passed to me?
