REST API Explorer - Did You Know

[@IqshitDhawan]

How can we add another approver in a request using API? The instance I am working on has a concept of Endorsement on UI, which is nothing but if an approver is not 100% sure about the request then they can request for endorsement which is a second level approval, once they approve/reject the endorsement, the request is back with the original approver to approve or reject. I noticed when we send a request for endorsement, it creates a new record in sysapproval_approvers table, but when I try to create a record in sysapproval_apporvers table using API, it creates a record but the Approver and Approving for fields values are not populating. I tried this on my service now developer instance as well the response is same. May I know what am I missing here?
