/// # Example
///
/// ```
/// # use bevy::prelude::*;
/// let mut app = App::build();
/// app.add_plugins_with(DefaultPlugins, |group| {
///    // The web asset plugin must be inserted in-between the
///    // `CorePlugin' and `AssetPlugin`. It needs to be after the
///    // CorePlugin, so that the IO task pool has already been constructed.
///    // And it must be before the `AssetPlugin` so that the asset plugin
///    // doesn't create another instance of an assert server. In general,
///    // the AssetPlugin should still run so that other aspects of the
///    // asset system are initialized correctly.
///    group.add_before::<bevy::asset::AssetPlugin, _>(bevy_web_asset::WebAssetPlugin)
/// });
/// ```
