Reference ID support for Paragraphs

I'm unclear on if this functionality made it to version 5.0.x. I have a Paragraph type in Drupal 9 that is related to a User (Parent ID would be user ID). I'm unable to expose this relationship when mapping the Paragraph to a Custom Object on Salesforce. I see all other Entity Reference fields, including the Paragraph Type, but not the Parent ID. Is this functionality not in version 5?

This fix somehow disappeared. This is not in version 5.

Is this still an issue?
