Mini 2- messages between inreach

Hello. i come from "mini 1" and to send messages between inreach it was necessary to send message to     [email protected] adress.

my question is: cuurently, with two users with "mini 2" and user of garmin messenger, if i send a message by garmin messenger to the phone number of the other inreach user, messages will be automatically delivered to inreach device if nor data or cellular connection? ior i have to continue to send to adress [email protected]  ?
