Xamarin.Forms open browser appending javascript

I am trying to implement a function in my project using Xamarin.Forms, in which it requires to open browser to targeted URI and append the value in the App's entry to the broswer website's input

I am currently using Xamarin.Forms' Device.OpenUri() method to open browser and i dont know if there is any way to append and execute a jquery script as we open the browser.

I imagine that it would be something like:

Device.OpenUri(new Uri("example.com")).AppendScript(<jquery script>);
maybe?

I have already search around for solutions but i only find the ones recommending "WebView" ways which not seem to suit my needs.

I appreciate all your help. Thank you!
