To get more flexibility, you can also create a [`WebhooksServer`] object directly. This is useful if you want to
customize the landing page of your server. You can do this by passing a [Gradio UI](https://gradio.app/docs/#blocks)
that will overwrite the default one. For example, you can add instructions for your users or add a form to manually
trigger the webhooks. When creating a [`WebhooksServer`], you can register new webhooks using the
[`~WebhooksServer.add_webhook`] decorator.
