Fees Refund 2021

Hi all, asking for a friend (copy pasted) I was an international student that unfortunately completed my entire course from my home country in 2021. I was eligible for a work permit and came in 2022 but since I didnt have a SIN during my course completion I never applied for the fees refund that CRA offers students. Can I still claim it? Any body that can help?

P.S: my friend started paying taxes recently when they got a job. I believe the course was a masters (if that matters)
