How to retrieve Business User's Roles using in-app extensibility in S4HANA Cloud?

Hello Experts, we are trying to developed a custom logic to Check Authorization to Change Project Stage (Engagement Project). We found the right BAdI but we need to check if the logged user has a particular Role assigned.

I'd like to know if someone has been able to found the right CDS View to select these values.

Thanks in advance for your cooperation.
