Cannot remove options from submenu

[Shawful]

Hello, I can add, but cannot remove submenu items. Please help. Maybe I'm just missing something, but I believe this should work.

const { Select, Input } = require('enquirer');

let submenuChoices = ['Option A', 'Option B', 'Option C', 'Back to Main Menu'];

const mainMenu = () => {
    const mainMenuPrompt = new Select({
        name: 'option',
        message: 'Select an option:',
        choices: [
            'Actions Menu',
            'Add Action',
            'Remove Action',
            'Exit',
        ],
    });

    mainMenuPrompt.run().then((choice) => {
        if (choice === 'Add Action') {
            addOption();
        } else if (choice === 'Remove Action') {
            removeOption();
        } else if (choice === 'Actions Menu') {
            submenu(mainMenu);
        } else if (choice === 'Exit') {
            console.log('Goodbye!');
        }
    });
};

const addOption = () => {
    const prompt = new Input({
        message: 'Enter a new option:',
        initial: 'New Option',
    });

    prompt.run().then((newOption) => {
        submenuChoices.push(newOption); // Add to submenu
        console.log(`Added new option: ${newOption}`);
        mainMenu();
    });
};

const removeOption = () => {
     const removePrompt = new Select({
         name: 'remove',
         message: 'Select an option to remove:',
         choices: submenuChoices, // Use submenu choices for removal
     });

     removePrompt.run().then((optionToRemove) => {
         // Remove from submenu choices
         submenuChoices = submenuChoices.filter((submenuOption) => submenuOption !== optionToRemove);
         console.log(`Removed option: ${optionToRemove}`);
         mainMenu();
     });
 };

const submenu = (backFunction) => {
    const submenuPrompt = new Select({
        name: 'submenu',
        message: 'Submenu options:',
        choices: submenuChoices,
    });

    submenuPrompt.run().then((selectedOption) => {
        if (selectedOption === 'Back to Main Menu') {
            backFunction();
        } else {
            console.log(`Selected submenu option: ${selectedOption}`);
            submenu(backFunction);
        }
    });
};

mainMenu();
