Is ara.apple.com a legit Apple Support means of screensharing?

I wasn’t receiving the prompts to start regular screen sharing so she made me use that website and I downloaded an app for screen sharing on my MacBook. Not sure if this was legit. I called them myself. There was that usual popup sent by the automated response in order to ID my devices. She didn’t send me any email as planned. Nor have I received a text message survey.
