I am using the package discord-modals to create better modals with my discord bot.

When I want to reply to the SlashCommandInteraction (actually it's the modalResponse listening event), then I can't make the reply ephemeral. When I remove the ephemeral bool, it works perfectly. But I don't understand why it doesn't work with a normal reply action.

await event.reply({content: `${replymsg}`, ephemeral: true});

So if I use this, I get the following error:

TypeError: Cannot read properties of undefined (reading 'EPHEMERAL')
    at ModalSubmitInteraction.reply (C:\Users\david_h7tqe3i\WebstormProjects\musicbottest\node_modules\discord-modals\src\v14\interfaces\InteractionResponses.js:51:57)

    at processTicksAndRejections (node:internal/process/task_queues:85:21)

Process finished with exit code 1

And if I use the following code, it works:

await event.reply({content: `${replymsg}`});
