Quicklaunch keyboard shortcut to start imessage high sierra

Hi, I have been using some of the automator and services methods to set up keyboard shortcuts to launch specific functions directly from the keyboard without being in an app itself, for example compose an Email from anywhere if I'm not in the email app directly. I was looking for a shortcut to do the same with iMessage. Initially I wanted to compose a new message, but it would be useful to simply launch the app as once the app is open, it is almost as easy to navigate to the recipient in question than to have a new window with a blank message on the screen. I'd also like some other universal shortcuts like launching safari or chrome from anywhere.

Thanks for your help with this!
