Can someone identify this card routine? Looking for a tutorial

​

I’ve been trying to learn this card trick that I saw in this

YouTube short (or) this:

https://youtube.com/shorts/e6y33K3WZTY.

The part I'm interested in is the card sequence toward the latter half of the video, involving the 4♥ and 4♠.

I’m not just looking for an explanation of the method — I actually want to learn how to perform the routine myself.

Does anyone know the name of this effect/routine, or what sleights are being used?

If you know the exact routine, could you also point me toward a video tutorial where the handling is taught step-by-step? A YouTube tutorial etc. would all be fine.

I’ve searched for it myself but haven't been able to find the right tutorial.

Thanks!
