Best Order Tracking Extension for Magento 2?

Does anyone have recommendations for an Order Tracking extension for Magento 2?

Something simple, with a couple of form fields (email and order number) to complete, and then if it’s valid and a match in our order database, we’d present them with their order status.

We’re currently getting inundated with “Where’s my order” inquiries from customers, so we’d like to provide them with a self-service option.
