How to use the figlet.fontsSync function in figlet

exports.run = (bot, msg, args) => {
    // -l -- List all fonts
    // -f <font> -- Set font
    const parsed = bot.utils.parseArgs(args, ['l', 'f:']);

    if (parsed.options.l) {
        bot.utils.textUpload(figlet.fontsSync().join('\n')).then(({ url }) =&gt; {
            if (!url) {
                return msg.error('Failed to upload fonts list!');
            }

            msg.edit({
                embed: bot.utils.embed('Available Fonts', `A list of available fonts can be found [here](${url}).`)
            }).then(m =&gt; m.delete(5000));
        });
        return;
    }

    if (parsed.leftover.length &lt; 1) {
        throw 'You must provide some text to render!';
