A friend of mine is going to have a video conference in Google Meet. At this conference she will be given some information in the conference chat and shown some documents. I'm not a participant of the conference, but she wants me to remotely watch her screen in real time during the conference, but in such a way that this can't be accidentally noticed by conference participants, who might ask her to share her screen at any time for the purpose of showing them some documents, or by people passing by her desktop or sitting nearby, who might have a look in her screen.
Is there a convenient way to do what she wants?
Our first idea was that she can have two video conferences at the same time, one in Google Meet with her conference participants and another one in Zoom with me so that she can share her screen with me via the Zoom conference, but the problem with this is that people might notice the Zoom conference on her screen. She wants to avoid that.
A few additional details: (1) she is prepared to give me any kind of remote access or control, so there are no trust issues between us whatsoever, (2) the sound is unimportant, so there is no need to transmit it or to ensure that I do not hear it, (3) our computers are Windows computers.
There may be a simple solution, but we are not very experienced users and humbly hope to get help here.
P.S. Although my friend's intention might seem somewhat ethically questionable, it actually isn't. The conference participants are not obligated or even expected to keep things confidential. She just doesn't want to make it obvious to other people that she is sharing her screen, so I'm asking to kindly focus on the technical aspect of my question.
UPDATE: In response to comments below, I'd like to emphasize that there's absolutely nothing illegal here. The conference is a meeting at which academic staff will discuss something with student representatives, who are expected to disseminate the information later as they deem fit, so there is no expectation of confidentiality whatsoever. My friend is a student representative, and the reason why she wants to share her screen with me in real time is that she wants me to have a look at documents, quickly analyze them, and help her quickly prepare a statement to be released shortly after the meeting. She doesn't want to show anyone that she has an "advisor" who helps her in such matters, and she wants to avoid being asked as to why she is sharing her screen.
