• preDownloadHook - A callback function to be called after a user has clicked the download button and before the download starts.
• displayFlavors - A flag indicating whether to display flavors to download. optional- default is true. if set to false then only the configured/default source will be available for download.

• displaySources - A flag indicating whether to display media sources to download. optional- default is true.

You can see the available flavor ids for an entry in KMC, and their matching If no flavor is selected, a default flavor would be downloaded.
