Requesting Support for Accessing Projects LOV REST API via Custom Role

We are currently facing an issue accessing the following REST API endpoint:
/fscmRestApi/resources/11.13.18.05/projectsLOV

The issue occurs when attempting to retrieve project LOV data using a custom role. However, if the user is assigned the "ORA_ASM_APPLICATION_IMPLEMENTATION_CONSULTANT_JOB" seeded role, the API successfully returns data.

As part of our investigation, I referred to the Oracle documentation:
🔗 https://docs.oracle.com/en/cloud/saas/project-management/25b/fapap/Job_Roles.html

According to the document, this job role includes the privilege: PJF_GET_PROJECT_LIST_PRIV.

Unfortunately, despite including this specific privilege in our custom role, we are still unable to retrieve data from the Project Number LOV API.
