Proof of Research

“ you have at least one example of research published or endorsed by an expert“

Can I use my masters degree certificate and thesis research paper (not published) as evidence for the above criteria?

Since it’s not published, you might need additional endorsement by expert
So I guess

  1. thesis research paper
  2. masters degree certificate
  3. reference letter from thesis guide / researcher [bonus if they are well established with lots of citations & great h-index
