Simulate Enter key in userscript tampermonkey

Question

I am trying to write a userscript that types something in input tag with class name="chat-input" and presses enter.The userscript as of now only types "Hello!" in chat-input but does not simulate enter key. Any idea why?

var msg = "Hello!";

        var target = document.getElementsByClassName("chat-input")[0];
                             target.value = msg ;
        var eventType = "textInput";
        var evt = document.createEvent("TextEvent");
        evt.initKeyEvent("keypress", true, false, window, 0, 0, 0, 0, 13, 13);

        target.focus();
        target.dispatchEvent(evt);

The input box does not have any submit button only way to send message is by enter key

Copying the answer with modification from here.

const ke = new KeyboardEvent("keydown", {
    bubbles: true, cancelable: true, keyCode: 13
});
target.dispatchEvent(ke);

According to that post, initKeyEvent is only for Firefox.

@CertainPerformance I didn't see the question as a duplicate question, they just had the same answer. But yeah, if you say so – Christopher Janzon Jan 07 '20 at 17:54
