I did an online shop like this through Informa, a couple of years before the pandemic. It was with a project manager I had done lots of work for, so I was not worried about a scam. We discussed what would happen for days ahead of time, and set an appointment for the shop (because he would have to be there).
I did it on my cheap laptop instead of my workhorse desktop, just in case. From what I recall, a financial company was having difficulties with their website--terrible thing for customer confidence in a business handling one's money. I went to the company's website, looked through their webpages for a specific product, and filled out an online request form, while the project manager watched what I did. Just basic info. We were on the phone at the same time, and I remember him asking me to open certain links on various pages.
The whole shop took about 15-20 minutes, with no shop form to fill out, and it paid three figures. Like shopperbob, I would not do a shop like this for an unfamiliar MS company employee.
