autodesk forge – creating issue with push-pin placement in ACC using POST issues endpoint

I tried multiple ways but cannot figure out how to add a placement that has a push-pin on a specific location in the linked document of an issue using the POST issues API endpoint. I tried placement array, linkedDocuments array but in both cases, the placement section of the issue is linked to the ACC document I want but it does not add the pushpin in the specified location of the placement doc.

Eg:

This creates issue with placement linking to the correct document

but the document itself does not have the pushpin

Expected:
The highlighted pushpin needs to show up in the linkedDoc /placement. Here I have created it using the “Click to add the issue pin”. I am unable to do the same via API.
