How do I resize my frame to fit a different platform/devie?

I’m new to Figma, and I was wondering how do I resize (scale) a frame to match devices?

I used constraints and things stay in place if I make the frame bigger/smaller in Figma, but when I go to presentation mode if I select a bigger device it doesn’t fill out everything, it just stays in the top left corner and grabs as much as it can.

There is no responsive preview in the prototype.

Well, that makes sense. Thanks for the answer.
