wireshark / ble sniffing 1st-timer... simple question

edit

I'm using Wireshark (Version 3.6.3 (v3.6.3-0-g6d348e4611e2) on an M1 MacBook and a Bluefruit LS Sniffer. I set things up following the directions here:https://learn.adafruit.com/intro...

After getting all the required pieces in place and launching Wireshark, I was shown a dialog that I thought asked me to choose the BLE packet types I wanted to see. I chose Advertisements (ADV?) because the first thing I wanted to see was what a particular device showed in a scan response.

Now I want to see other types of packets going back and forth between my device and my mobile app, but I cannot find that original dialog, or some other, that will allow me to observe service and characteristic discovery, etc.

Can someone help, please?

Thanks you!
