Keying either individual letters or an entire word into hangman game

I am currently creating a hangman game for a project. I have managed to code where a user can enter individual letters to guess the secret word. However, I am having trouble adding an additional feature where the user can guess the entire word upfront.

below is my code attempt, may I know what to write to have this new feature in my game?

def game_play():
    word = random.choice(WORDS)

    # Dashes for each letter in each word
    current_guess = "-" * len(word)

    # Wrong Guess Counter
    wrong_guesses = 0

    # Used letters Tracker
    used_letters = []

    while wrong_guesses < MAX_WRONG and current_guess != word:
        print (HANGMAN[wrong_guesses])
        print ("You have used the following letters: ", used_letters)
        print ("So far, the word is: ", current_guess)
    
        guess = input ("Enter your letter guess:")
        guess = guess.upper()
    
        # Check if letter was already used
        while guess in used_letters:
            print ("You have already guessed that letter", guess)
            guess = input ("Enter your letter guess: ")
            guess = guess.upper()

        # Add new guess letter to list
        used_letters.append(guess)

        # Check guess
        if guess in word:
            print ("You have guessed correctly!")
    
            # Update hidden word with mixed letters and dashes
            new_current_guess = ""
            for letter in range(len(word)):
                if guess == word[letter]:
                    new_current_guess += guess
                else:
                    new_current_guess += current_guess[letter]
                
            current_guess = new_current_guess
        else:
            print ("Sorry that was incorrect")
            # Increase the number of incorrect by 1
            wrong_guesses += 1
        
    # End the game
    if wrong_guesses == MAX_WRONG:
        print (HANGMAN[wrong_guesses])
        print ("You have been hanged!")
        print ("The correct word is", word)
    
    else:
        print ("You have won!!")
