How to connect the device using AT commands on the esp32 LilyGO T-SIM7600G to HiveMQ Cloud

HiveMQ Cloud

I was following this user’s guide on arduino: https://forum.arduino.cc/t/sim7600g-h-mqtt-at-cmqttconnect-error/1050860, but I have an error in the following command:
AT+CSSLCFG?

+CSSLCFG: 0,4,3,1,300,“cacert.pem”,“clientcert.pem”,“clientkey.pem”,1,“”,0xFFFF
AT+CMQTTSTART
OK
//I copied the certificates from the link left by hivemq https://drive.google.com/file/d/1VfNZ1wWcXvRzuSCx7WtNGJxW1jq_R7nk/view, assuming that the order is as follows: carcert,client,clientkey
+CMQTTTTSTART: 7 // What does number 7 mean?
