I cannot connect to IQ Panel 2. It asks for Register Gateway?
MyQ devices are not paired directly with the IQ Panel.
It looks like you have MyQ support on your plan so you are good there.
To get started adding a MyQ Garage to your account, login to the Alarm.com website in a web browser (not the app) and navigate to Settings > Manage Devices > Add Device.
After registering your MyQ devices in Alarm.com they will automatically sync with your IQ Panel.
A MyQ gateway must be deleted from the MyQ app first if it is registered there.
