Declaration Warning on WCS_Query Class

[stdmedoth]

When try install the plugin, i get the Warning: Declaration of WCS_Query::get_endpoint_title() should be compatible with WC_Query::get_endpoint_title(, = '')

If we analise the WC_Query Class on Woocommerce /**

• Get page title for an endpoint.
• @param string $endpoint Endpoint key.
• @param string $action Optional action or variation within the endpoint.
• @since 2.3.0
• @since 4.6.0 Added $action parameter.
• @return string The page title. */ On WooCommerce 4.6.0 the $action parameter was added, On WooCommerce Subscriptions 3.0.10 this warning was fixed.
