Can anyone help me understand these questions around AOC on Jan 6? Jan 6th right as Donald's speech was winding down:

1. CSPAN was showing live video footage of Mike Pence in front of Congress while Representatives were making arguments, I recall Matt Gaetz and Marjorie talking to the Congress before they were evacuated. Question: I'm assuming this is a meeting that had all the representatives present. Why wasn't AOC present?
2. I also recall tweets from Representatives saying that Pelosi had been escorted out followed by the rest of the representatives through the tunnels. Lastly their were tweets thanking security and posting pictures, it seemed the representatives were held up in some secure space elsewhere in DC and were having lunch delivered and just relaxing while enjoying some food. Question: Why wasn't AOC escorted out of the building with the rest of the reps and why was she the only one that was personally under attack? Shouldn't there be multiple stories of many representatives having run ins with terrorists?
3. I'm assuming the answer is that she skipped out on the hearing and was in her personal office elsewhere for some reason, and like the story says it was police that were looking for her to secure her. Question: Why hasn't this occured to AOC yet that there were no terrorists at her private office. Why hasn't anyone she knows helped her understand that only the Capitol Dome building was breached by protestors?
