I couldn't find it from the article, but how the scammer got access to the Gmail account? How he triggered that prompt in the victim's phone, and what did it mean?

It feels something is missing here?

Edit: Well, I learnt about Google Prompts today: https://support.google.com/accounts/answer/7026266?hl=en&co=...

Basically someone can request access to your account and if you click Yes, they do access it.

This part from a Reddit thread [1] scared me a bit:

> The notification pops up on my screen over whatever I am doing, and if I'm using my phone, I worry that I might accidentally hit YES (it almost happened today).
