I cannot set item id in auto value on save of the Advanced Resource Template Module

Hi everyone.
I am trying (for hours) to set the following on the dcterms: identifier field with no luck

On item save the identifier is populated with “https://example.com/entity/” but the {o:id} is not populated.
I have tried several options such as {{ o:id }} {id} {o:item.id} but nothing works.
Can you please elaborate on this? My goal is to set dcterms:identifier to get automatically the value of the current item id

Thank you in advance
