Tutorial on Losant and IoT

I would like to expand my knowledge on IoT and came across [login to view URL] as an interesting platform to experiment and learn. I have gone through their web tutorials but I still lack understanding on certain concepts and terminologies. I am looking for someone who has already worked with Losant who can tutor me as to its working, in particular using MQTT and Losant brokers, edge devices etc., and testing with Chrome MQTT lens. Looking for 1-2 hours of tutoring. Thanks.
