I want to add inspection tool in my browsing app on android studio Kotlin

Question

in my browsing app on android studio Kotlin

I used this script of enable the inspect tool in browser.

javascript:(function () { var script = document.createElement('script'); script.src="//cdn.jsdelivr.net/npm/eruda"; document.body.appendChild(script); script.onload = function () { eruda.init() } })();

But still it is not enabling the inspection tool.
