Trying to Change WiFi network but stymied by 5 digit code

We have a RING doorbell/Camera that has been installed since 2021.  The device works fine, but when I check the Wifi Connection signal strength it is generally in the low 60's.  Since we have some other devices that have some connection issues, I recently purchased and installed a WiFi extender.  I am now trying to connect the Doorbell to the 2.4Ghz band of the extender.  So within the App when I go to device health and change Network, the app ask for location info, and if I am close to the device.  Once I confirm that there is a White Circle on the device, the App asks for a 5 digit PIN located under a QR code.  I can't find a QR code anywhere on the device to find this PIN.  Do I have to dismantle the installation to get to this code?  Help.....
