WooCommerce: Assigning an endpoint to a custom template

This function adds a tab named "Special Page" into "My Account" tab list:

add_filter( 'woocommerce_account_menu_items' , 'jc_menu_panel_nav' );

function jc_menu_panel_nav() {
    $items = array(
        'dashboard'       => __( 'Dashboard', 'woocommerce' ),
        'orders'          => __( 'Orders', 'woocommerce' ),
        'downloads'       => __( 'Downloads', 'woocommerce' ),
        'edit-address'    => __( 'Addresses', 'woocommerce' ),
        'payment-methods' => __( 'Payment Methods', 'woocommerce' ),
        'edit-account'    => __( 'Account Details', 'woocommerce' ),
        'special-page' => __( 'Special Page', 'woocommerce' ), // My custom tab here
        'customer-logout' => __( 'Logout', 'woocommerce' ),
    );

    return $items;
}

That results in this:

But the link points to my-account/special-page/, and naturally gives a 404 error.

How I can assign this URL to a file named special-page.php?
