How can I add an .mp4 to a Widget Blueprint?

Title says it all. It’s pretty much a video background for my to-be main menu. So, how can I add an .mp4 to a Widget Blueprint?

Bumperooo.

Another bump.

Another bump? Woah.

Please dont bump so often so quick. It is weekend so both AnswerHub and forum traffic is slower than week days.

And please check out the documentation first: Media Framework | Unreal Engine Documentation

Sorry, still pretty new.
And thanks a bunch.
