Im trying to make my website change view from mobile to desktop view using a button in javascript

const handleClick = () => {

      const viewport = document.querySelector("meta[name=viewport]")
      viewport.setAttribute(
         "content",
         "width=200px, initial-scale=1.0, maximum-scale=2.0, user-scalable=0",
      )
}

I am using this code and it changes the viewport in html when I inspect using chrome but the screen is not changing
