How to prompt user to try to input again

Question

Here is my code. I am wondering if there is a way to prompt the user to try to input a title again if they fail to meet the requirement of being less than 200 characters long. Thanks for any help!

message.author.send(
 'Lets get to work!\nPlease enter the title of your event. (Must be shorter than 200 characters)'
);
message.channel
 .awaitMessages(
  (response) =>
   response.author.id === message.author.id && response.content.length < 200,
  {
   max: 1,
   time: 10000,
   errors: ['time'],
  }
 )
 .then((collected) => {
  message.author.send(`I collected the message : ${collected.first().content}`);
  let title = collected.first().content;
 })
 .catch(() => {
  message.author.send('No message collected after 10 seconds.');
 });

You could put it in a function, then just repeat the function over and over again.

message.author.send(
 'Lets get to work!\nPlease enter the title of your event. (Must be shorter than 200 characters)'
);
const collecter = () => {
 message.channel
  .awaitMessages(
   (response) => response.author.id === message.author.id, // remove requirement from function
   {
    max: 1,
    time: 10000,
    errors: ['time'],
   }
  )
  .then((collected) => {
   if (collected.first().content.length < 200) {
    // add it in the callback
    message.channel.send('bla bla bla went wrong! Please try again');
    collector(); // repeat the function
   }
   message.author.send(
    `I collected the message : ${collected.first().content}`
   );
   let title = collected.first().content;
  })
  .catch(() => {
   message.author.send('No message collected after 10 seconds.');
  });
};

collector();
