How would I detect oxidation in an oral semaglutide vial without sending it to Janoshik?

The case in front of me: oxidation · oral semaglutide · Janoshik.

I have done this once and I suspect I got away with it rather than got it right.

For context: I keep records of every batch, every lot number and every result, so an answer that requires me to track something is fine.

What is the correct sequence, and where is the step that people usually skip?
