Expired re entry visa and iqama. How to come back on same company?

good day what would be the application process and rules to obtain a fresh working visa for the same company which issued the reentry permit and iqama that lapsed.

Actually my employer talkes to me already and he said that they are trying to get a new working visa for us since my re entry visa and iqama is already expired. I dont know if we can still go inside the kingdom with this kind of situation amd if anyone of you gas can help me regarding on this matter, we thank you so much.
