TeamViewer 15 URL/Link to Start a Remote Connection

We have been using the URL format teamviewer10://control?device=xxxxxxxxx but now with TV 15 the app launches but fails to start a connection to the specified device. This is running on Teamviewer v15 using the new GUI. Did the format change for this or is this function not working correctly?
