How to extract MQTT message from the Simple_MQTT sample for nrf9160-DK?

I am trying to use a specific message to trigger an action based on a predefined string.
Not sure how to extract the string from the MQTT message. I'm using Mosquitto for publishing messages the the DK and it recieves and echoes the messages based on my predefined topic.

Anyone familiar with this?

Use one of the read publish functions when you receive a publish event like in the sample.
https://docs.zephyrproject.org/latest/reference/networking/mqtt.html#_CPPv425mqtt_read_publish_payloadP11mqtt_clientPv6size_t
Then you'll have to string match on the buffer you`ve readout.
