It seems to me that it is not necessary to show a copy of the certificates you have obtained in your career as an academic or researcher. His own works speak of his professional development and ability.
Personally, I don't want to upload my certificates on RG. I don't think those who upload their certificates do it to win more reads and recommendations. It's probably to inspire others. If such scholars did so because of scores, then it's really unethical.

There is no need for showcasing in the academic world. It is usually the content of one's research not education credentials that influences the readership.
