What is this button no qualified pilot would press?

[Mr70]

A pilot who lied about his flying experience to secure a job at British Airways,was said to have been caught when he pressed a button that no qualified pilot would have pressed,but nowhere does it mention what button that was?https://www.businessinsider.com/brit...-button-2022-4

Thanks,I was leaning towards EJECT button,but seeing as this is a commercial airliner,thought more likely the ABORT FUEL button.
