How to get clipboard data in javascript while pasting it.

I have a iframe which is used as rich text box editor means entered text can be bold/italic/underline.

if user paste data in this frame I just want to put some restriction on that data before pasted. like if user tried to paste some script or some restricted XSS content just restrict them.

The solution should work for chrome and edge browser.

Thanks,

What I have tried:

I have tried below code-

iframeElement.addEventListener('paste',function(e){
var text=e.clipboardData.getData('text/plain')
// put validtion
// then prevent to paste
e.preventDefault();
// show error message to user
});
