From HA to SmartThings

So I have the Smartthings integration configured in HA and that works fine, all my ST devices show up and work as expected in HA.
Can I somehow go the other way around? Get a few devices to show up from HA into SmartThings (the way you can add HA devices to Alexa)
I need to get a gate switch from HA to show up in SmartThings so I can open it from my Galaxy watch (from the SmartThings app on that)
