Problem add Device ADS1115

I’m new to the community and new to the world of programming.
my problem is that Cayenne does not add me the ADS1115 device.
ADS1115 is correctly connected on the raspberry and with i2cdetect -y 1 the device is addressed as 48.

I attach screenshots of the Cayenne problem

Extensions are not supported on Raspberry Pi Agent 2.0

so I can not use it?
how can I do? could I have a support?

I installed Cayenne-MQTT-Python. I do not know how to proceed

Next try to get the reading from ADS1115 using ADS1015 / ADS1115 | Raspberry Pi Analog to Digital Converters | Adafruit Learning System

I can read from ADS1115, my data is writing them to a local database. what I do not understand is how to make cayenne talk with ADS1115. could you give me an example? I miss a passage.

look at this example on how to send and receive data from cayenne Cayenne-MQTT-Python/ at master · myDevicesIoT/Cayenne-MQTT-Python · GitHub
