How can a telegraf library send an inline menu without text in front of it?

Question

JavaScript

Here is the trigger with the response

bot.hears('/main', (ctx) => {
  ctx.reply('hi ', frontMenu());
});

but I'm interested in what would be without text on top of the keyboard (example below) - but it doesn't work, swears at empty text, is there any other function to call only Claudia?

bot.hears('/main', (ctx) => {
  ctx.reply('', frontMenu());
});
