Answer 1

This works in Dec 2019. Original snippet by Shubham modified by Cami Rodriguez (see comments above).

function write_in_chat(text) {
   var input = document.querySelector('#main [contenteditable~=true]');
   setTimeout(() => {       
      input.innerHTML = text;
      input.dispatchEvent(new Event('input', {bubbles: true}));
      var button = document.querySelector('button>span[data-icon="send"]').parentElement;
      button.click();
   }, 500);
}
