@Sai Kumar P  try the below script, just an idea.

function onLoad() {
  // Replace "text_area" with the ID of the multi line text variable
  var element = gel('text_area');

  // Add an event listener to the element to update the counter in real-time
  element.addEventListener('input', function() {
    var remainingChars = 200 - element.value.length;

    // Replace "char_count" with the ID of the HTML element that displays the character count
    gel('char_count').innerHTML = remainingChars + " characters remaining";
  });
}
