I can't find 'gear VR' in 'plugins' menu

In tutorial, it said to use unreal engine with Samsung gear VR, set ‘gear VR’ plugin at first.
But when I open Edit tab - Plugins, I cannot find gear VR. There are only google Vr, google VR transition 2d, mixed reality framework, oculus vr, osvr plugin, sample mesh reconstructor, simpleHMD, and SteamVR.
How can I use Samsung gear VR in unreal engine?
