Open link in another browser

<button>open in another browser</button>

 

const btn = document.querySelector('button') 
btn.addEventListener('click', () => {
    window.open('https://example.com', '_blank')
})

Assume the HTML button above will be viewed in an Android WebView.

I need the link to open in an external browser. For this, I know that it is necessary to program both on the front-end and on the back-end.

In Java, for another application to open the link as expected, you need to use Intent, as shown in this post:

What I need to know is how to program JavaScript so that _blank is understood by Java as a link that must be opened externally.
