How to insert already “clean” text into the field if it was formatted in the buffer?

Question

JavaScript

I'm trying to "clear" it from tags when pasting text into a field from the buffer, but after execCommand('paste');that the code stops doing anything?
Tell me how to fix this? Or maybe there is another way to solve this issue?
Thanks in advance)

Code on jsfiddle.net

HTML:

<textarea id="txtInput0"></textarea>
<br/>
<div id="txtInput" contenteditable="true" ></div>

CSS:

#txtInput0{
    width: 200px;
    height: 30px;
}
#txtInput{
    width: 300px;
    height: 60px;
    font-size:20px;
    background-color:lightgrey;
}

JS:

$(document).keydown(function(event) {
        if ((event.ctrlKey) && (event.which == '86' || event.which == '118')) {
            if($('#txtInput').is(':focus'))  {
                
                $('#txtInput0').focus();
                $('#txtInput0').select();
                execCommand('paste');
                $('#txtInput').html($('#txtInput0').text());
                $('#txtInput').focus();
                
        }}});

Have you looked in the direction of a slightly different solution for inserting text?
