To call an action from an HTML form, add `method="POST"` to your `<form>`, then set the form's `action` attribute using your action, for example `action={actions.logout}`. This will set the `action` attribute to use a query string that is handled by the server automatically.

Note: If your form includes file uploads, you must also add `enctype="multipart/form-data"` to the `<form>` element. This ensures that files are sent in a format that allows Astro's schema validation library to correctly recognize `z.instanceof(File)` inputs.

For example, this Astro component calls the `logout` action when the button is clicked and reloads the current page:

```astro title="src/components/LogoutButton.astro"
