OHIF plugin for Orthanc user configuration

I’m using OHIF plugin for Orthanc v1.2 and trying to autoplay cine files but it does not seem to work. In fact, it appears none of the options in my config are working and it leads me to think that I might be doing something wrong here.

Here’s my config ohif.js file

window.config = {
  extensions: [],
  modes: [],
  showLoadingIndicator: false,
  autoPlayCine: true,
};

and I configured the plugin in Orthanc as follows:

{
  ...
  "OHIF" : {
    "Datasource": "dicom-web",
    "UserConfiguration" : "/etc/orthanc/ohif.js"
  },
  ...
}

Thank you for your help!
