Example code not working

Hello All, I am trying to get a Soil moisture sensor working. It is one of my first projects so if yyou would please help me out I would so appreciate it. I went to the cayenne dashboard, added a new custom gauge widget with data set to soil moisture and on channel 0 (not sure what channel 0 is…but thats not my question.) When I click the step:1 Code it returns the example below. This code on my arduino ide is returning an error of CayenneMQTTClient.h: No such file or directory although I have gone to sketch>manage libraries>cayennemqtt. I also saw this error when i searched google and someone helped figure it out https://community.mydevices.com/t/cayennemqttclient-h-no-such-file-or-directory/13136

you need to use this library https://github.com/myDevicesIoT/Cayenne-MQTT-Arduino and select the type of connection code from the example folder.
