How can I implement a toggle `AppIntent`?

To implement a toggle AppIntent, you should structure your intent to support toggling between two states, such as turning a feature on or off. This is particularly useful for intents that only change between two states, like a flashlight app that toggles the flashlight on or off. By supporting toggle as the default parameter, the intent can switch states without needing to ask the user each time.
For example, if you have an intent to toggle a feature, you should:
- Define the intent with a parameter that supports toggling.
- Set the toggle as the default parameter to allow the intent to switch states without additional user input.
