This is the kind of stuff people send to me and then I have to explain the many reasons why we can't do this.
First, that section of wall now doesn't have insulation and wouldn't be up to code in most states.
Second, I don't see a header over that wall cavity.
Anyway there are ways to do stuff like this, but random videos (and increasingly, AI photos that have no basis in reality) don't mean you can automatically do whatever they're showing...
