Video error

I have also question reg. videos. I’m newbie and gonna make a prototype of a design studio’s website.
There should be inserted a grid of promo videos stored at YouTube channel and embedded into the page. Well, it should look like the grid of videos under “portfolio” of this animation studio example. I.e. it’s expected to be available both for preview at the web-page and for playback by getting to YouTube.
So I’m confused now abt the way to embed it into my prototype… I guessed, I should use the @SohrabNiroo ‘s recommended adding video guideline. Though, it shows the way with uploading the video to Figma’s canvas, but I don’t need it. I checked through the forum and ’ve found another thread abt the inserting video, but it’s also not solution for my case.
Any ideas for making the described prototype, containing videos grid? I’d highly appreciate any advice or tutorial.
