I thought of the whiteonwhite option but you can see the value if you select the record.
as the business rule - I don't think I have the logic quite right as it is supposed to change
as it moves through the approvers and then goes blank when not in the status.
at the moment I'd be happy if it just moved through the approvers
Here is a quick action which will grab all the approvers from pending approvals so you can put them in a field. You can call the quick action either on an update of the change record or use run for child so when the FRS_ApporvalVoteTracking object updates it runs for child to the FRS_Approval object which in turn runs for Child to run the update quick Action on the change Object.
$(ChildFold("Change#", RecId, "FRS_Approval#.ChangeAssociatedFRS_Approval", $(ChildFold("FRS_Approval#", RecId, "FRS_ApprovalVoteTracking#.FRS_ApprovalContainsFRS_ApprovalVoteTracking", $(OwnerFullName + " "), "+", $(Status == "Pending"))), "+", $(Status == "Pending")))
