title: ARCore: The application does not have permission to use the Tango 'Dataset Read/Write' capabilities
body: <p>Im am getting the following error when attempting to implement a native plugin in Unity. I have this plugin working in both a standalone Android application as well as a VR implementation so I think this is a specific ARCore permission issue. I am not familiar with how Tango is implemented with regard to ARCore:</p>
  
  <blockquote>
    <p>W/tango: permission_handler.cc:76 The application
    'com.midtablestudios.'ApplicationName'' does not have permission to
    use the Tango 'Dataset Read/Write' capabilities. To ask the user of
    your app for this permission, invoke the Tango Android permissions
    intent for 'Dataset Read/Write'.</p>
