Is it possible to get all the records on Team subtab in Subscription via groovy or REST api?

Summary:

We want to get all the records on the Team subtab under Subscription.

Content (required):

We want to get all the records on the Team subtab. But we can only get those who are tagged as Owner using the SubsciptionOwnerVO via script. We cannot find the REST endpoint for this subtab.

We just want to know is it possible to get all the records via groovy or REST api.

Thanks.
