URL construction

URL construction

Hello,
I have a function that creates a new record and then after that opens the record for editing.
This is the tail of my function
  1. //fetch newly created record
  2. newRecord = Register[ID != 0] sort by Added_Time desc;
  3. //open record for editing
  4. openUrl("#Form:Register?recLinkID=" + newRecord.ID + "&viewLinkName=Beneficiaries","popup window");
This sort of works, however it's derived from the original app in the older Creator version and I have no idea where the &viewLinkName=Beneficiaries refers to. But if I remove it it doesn't work, then it just opens a blank form.

Does anyone understand where viewLinkName comes from or what it does? Because also when i then Update the record, it shows a success message that was originally configured but not any longer. So I don't get it :) Is it some hidden code that I can no longer access, but still somewhere in the background?
All I want is to open the newly created form.
