A quick message button to the author of a typo / inaccuracy post

I would like to be able to see the topic and the error in it - quickly inform the author of the topic about it.
Best of all for this would be a button under the post, where the name of the author and the vote was appropriate.
I pressed the button - the input field was opened - I wrote what was wrong, clicked “send”.
Less rubbish in the comments, faster and more feedback to the author about the quality of the content.
