Can't intergrate with RemoteDatabaseSupport plugin

Empty UE project with blueprints and C++.

I’m trying to add plugin from doc
https://docs.unrealengine.com/en-US/API/Plugins/RemoteDatabaseSupport/index.html

The problem is that I’ve got an error:
Unreal/UE_4.25/Engine/Plugins/Runtime/Database/RemoteDatabaseSupport/Source/RemoteDatabaseSupport/Public/RemoteDatabaseConnection.h(6): fatal error C1083: The file is not included in the include search path: Database.h: No such file or directory.
