Salamun Alaikum! Hope you are doing well. We are sorry for replying you late.
The intention of “Qurbat” means you hope to get closer to Allah when you do prayer or any good deed. The daily five time prayers are wajib, Adhan and Iqama are mustahab. Reciting Ali un wali ullah is not part of Adhan and Iqamat. We do it hoping Allah will reward us more for this deed.
