What’s your garage door opener model?
If it’s already integrated with SmartThings all you need to do is add open garage door to your I’m Back routine which is triggered when you return home (using your phone as your presence sensor).
See this thread for ideas if you’re using a Linear Garage Door Opener
If you’re using a MyQ or Chamberlain you can use Routines to trigger them.
