Screenly OSE Support for Headers (for Grafana Auth)

I’m using the latest Screenly OSE from master (f2cbd9f) and I don’t see the functionality referred to in this post about adding headers to assets:

I don’t see an “Advanced” option when adding an asset. Is this only in the pro version? Is it available in the experimental OSE version?

That’s because you are confusing the two, screenly-ose and the commercial version of screenly mentioned in that article…

With Screenly, it could not be easier to view your Grafana visualizations on the wall. Once you have your Screenly Pro player up and running, you can manage everything from Screenly’s web interface.
