How to embed videos in Shiny

So, I'm seeing a pattern that the best practice is to simply use HTML and iframes. Am I right?

Also, I tried to put this video

https://drive.google.com/drive/folders/1VDslSm_Hm0Iz14_hlosP5QFzsoric-PO

into the app and it shows the space where the video would pop up, but it doesn't play. I know the video is saved in Google drive. Is that a problem?

And thank you Hadley for responding, you're a legend!
