Scammer gained access to my machine

I was having problems with my printer, so I went to a website to find a driver for the printer and started to search for the driver. I got a pop up messaging app asking if I wanted help. I messaged with them back and forth and they asked me to install the "Support - LogMeInRescue" app which I did. They then asked for access to my machine through that app and proceeded to look over my machine. I became concerned when she opened System Information on the my Mac Mini and then went to Software > Logs > WiFi log where she lingered over the information there for a while. I asked why she was not looking at one of the Printer Logs instead and then asked her to confirm she is affiliated with the printer manufacturer as I was getting suspicious. She responded that they are independent tech support and then disconnected.

My question is whether I should be concerned? She did not install anything or have time to do anything else other than look at the "About This Mac" screen and the WiFi log (as far as I could tell).
