Both the free and premium version of YITH Advanced Refund System for WooCommerce fully support Elementor page builder.
So, when you edit your pages from Elementor panel, you will be able to find the following two widgets under YITH menu and edit them through Elementor settings:

1. YITH Advanced Refund System – Refund Requests: this prints all the refund requests in My account and let the customer see all his/her requests in one place.

2. YITH Advanced Refund System – View Request: use this widget if you want to show the status of a specific refund request on a page that can be quickly created by the admin. Just make sure you add the refund request ID to make the widget visible.
