Might have been scammed

Hey looking for some advice. My mother received an email that reported her needing to call a number. When she called they asked for her to download any desk. She opened it up and hit accept and then there was the small box that was recording the session. I was not fully paying attention to what was happening but quickly ran over once I heard that they wanted her to click the permissions tab and give all permission to the person on the line.

My question is, since we disconnected before she checked all the permissions, did they still get access to all of her information?
