If I put a custom property in a headline, e.g.
(org-element-put-property headline :EXPORT_FILE_NAME "a")

Then, when accessing the org element headline it shows: :EXPORT_FILE_NAME a

However, when I proceed to interpret the data,
(org-element-interpret-data headline)

The custom property does not exist in the properties drawer.


Is there a way of modifying custom properties of a headline by using
org-element, and have the custom properties show up when interpreting the
data?
