Do While loop challenge

Hey guys. I'm looking for any help with this challenge. I understand the concept behind Do While loops, but I can't seem to put this code together to pass this challenge. What I have attached probably isn't close to the answer, but i'm going to move on for now. Anything helps, thanks.

script.js 
let guess;
let secret = sesame;
correctGuess = false;

 do {
  guess = prompt("What is the secret password?");
   if ( secret === sesame ){
     correctGuess = true;
      }
} while ( ! correctGuess )


document.write("You know the secret password. Welcome.");

You shouldn't need to create any new variables for the new version (like "guess" or "correctGuess").

Hint: Try re-using (but re-ordering) the original lines to create the new version, it might help avoid some of the syntax errors introduced here and keep the code more compact.

FIRST, erase everything in the script.js. The instructions on there are confusing as heck! But I understand that we need to use the do - while loop. The loop consisting of the prompt to capture what the user inputs. We must keep showing the prompt until the user enters sesame into the prompt field. Ok so lets do it!

let secret;  // create an empty variable for secret.

do { // start the do statement
    secret = prompt("What is the secret password?"); // assign prompt() to secret and show user the field to enter answer.
  } while (secret !== "sesame"); // check user input if `sesame` entered othewise run do {} statement.

alert("You know the secret password. Welcome!"); // if answer if correct display alert message.
