I created a stream link for Disney+ by creating folder /Channels/Imports/TV/DisneyPlus. In that folder I created 0x00.strmlnk with the text below in the file.
The artwork that Channels displays is generic. It would be great if we could create custom artwork and descriptions or Channels use the site's artwork / favicon and description.
Another possibility would be to have something similar to a .strmlnk but use a .JSON file that contains the URL link, link to the artwork file and description text.
