How to get Alexa to control my GoControl garage door opener

[Albert_Santiago (Ponch Santiago)]

Linear GD00Z-4 GD00Z-4 Z-Wave Garage Door Opener--

Installed the Linear GD00Z-4 GD00Z-4 Z-Wave Garage Door Opener, it worked fine with open/close when people arrive/leave. Only one thing I can not figure out how to make it to work: When performing “Good night”, I want it to close ifit not closed yet. But the “garage door” did not not show up in the “Garage doors” section (ST says no available options), Instead, the garage door opener showed up in the “light or switches”. Does anyone know how to fix this? thanks!
