ManifestV3: How do I access the Youtube, Streamable, etc embeds for iframes?

[animber0]

The CSP blocks all of that (trying to access embedded video via iframe from external sites).
Am I supposed to reference external scripts somehow? Seeing a lot of rejection by the CSP, but but it looks like ManifestV3 is against this sort of external loading too, is there someway I should be doing this?

This is an issue specifically with inline players (like a custom component wrapping Player.js or an npm package affecting the same). Just use a raw iframe or video element for testing purposes, that's as far as I got.
