How would I go about showing a video with anvil?

Thank you for the PoC @divyeshlakhotia !
Unfortunately I haven’t been able to make it work.
Opening the app I saw a notification saying some features were for payed memberships only…
The app still ran with no errors so I tried implementing it in a similar way but I think I am missing some things.

What are these lines for ?

import anvil.js
from anvil.js.window import document
