What is the Rest API to read and update Assessment level Descriptive Flex fields?

Summary:

We have descriptive flex fields configured at the Assessment Level (POQ_ASSESSMENTS) in Supplier Qualification.

We need the REST API to read and update one of these Assessment level flex field.

We used the 'Search for active initiative' API (curl -u username:password "https://servername/fscmRestApi/resources/version/supplierInitiatives/300100188274479") available on this link: https://docs.oracle.com/en/cloud/saas/procurement/24a/fapra/use_case_manage_supplier_initiatives.html

But this fetches only Initiative level details.

Please share the REST API to read and update Assessment level details.
