How to get additional content on UE Linux?

Linux seems to be missing the launcher (bug or feature?)

Is there any way to download the learning examples without launcher? Can somebody make those available? We are looking at how to get the sample content (e.g. Open World, Particles, Automobile Shader Collection)
Here seems to be a list: Engine Feature Examples | Unreal Engine Documentation

Could that content be added in Github for us to download and use as a work around until this is fixed?
