How to capture lte params

Hello, I tried using this in provisions and I reviewed the debug file and I still couldn’t capture lte parameters from the device, how can i do that?

InternetGatewayDevice.X_AVS_EXT.WAN.LTE.RSRQ is the path of the parameter and I took it from avs system.

if it’s really present you should be able to read it as mentioned in the instructions

also you should be able to see it and refresh it under GenieACS UI
