Issue on Talent Profile REST API

Hi All,
We try to fetch from Talent Profile REST API the profile section id about employees but the section is not present on the API response as defined in the attached file.
The section is a custom section and it 's defined in the attached file.
The section becomes visible only if we insert a dummy record from HCM user interface and then we delete it.
Since, the business requirement is to create the certification from API directly, we need the certification section to be always present in REST API response without any manual activity because we can't create a manual record for all employees.
