HSM Open Contact Notification to HD+(Android Dashboard)

How would I go about entering info in HSM to tell it to send a message to display in HD+(Android Dashboard) that a contact is open (door/window) when I want to arm the system?
I am using 3 Amazon Fire 7 (12th Generation) tablets and a Hubitat C7.
I am new to all of this and find that most of this is way over my head.
So please be gentle.
