To add to the site a call to Apple Messages just by inserting the link:
<a href=""imessage://ваш@appleid.com"">to Send an iMessage on Mac</a>
or for iOS:
<a href=""sms://ваш@appleid.com"">Send message on iOS</a>
Can I somehow pass its a placeholder(or just a message)? That would be when the user opened the message, on the screen in this messenger show "Hey, we're such a team! how can we help you?"
