Qualtrics code snippet.

I have received the qualtrics java code snippet for the survey created, but I'm not quite sure how to use it.
I have a react app and I would like to show the survey in a pop up that will open after click on a button.
I was checking some info and I see that the only thing I should do is to create a IFrame element and in its source property copy and paste the anonymus survery link.
now my question is, in order to embed the survey in a pop up in my react app I only need the anonymus survey link? If so, how must I use the java code snippet that I received?
