Set Minimum and Maximum Zoom on WKWebView or Disabling it entirely

What I want:



I'm trying to figure out how to set the minimum and maximum zoom onWKWebView.
I've searched through a lot of people who asked similar questions but no solutions has worked in my code.
If there is no option to set the minimum and maximum zoom, I would like to know how to disable zoom on WKWebView entirely.
