How to use existing HTML files in React Native

I have designed my app using HTML and CSS. I’d like to “copy” it over to React-Native and keep all the formatting and styling. Is there a tool or best-practices method when doing something like this?
I have tried rendering Raw HTML with packages like
react-native-html5 - https://www.npmjs.com/package/react-native-html5,
react-native-render-html - https://github.com/archriss/react-native-render-html,
webview -https://reactnative.dev/docs/webview
but none makes the view interective.

My RawHTML look like this

 <html>
   <body>
    <h2>HTML Forms</h2>
    <form>
    <label for="fname">First name:</label><br>
    <input type="text" id="fname" name="fname" value="FristName"><br>
    <label for="lname">Last name:</label><br>
    <input type="text" id="lname" name="lname" value="LastName"><br><br>
    <input type="submit" value="Submit">
    </form> 
  </body>
