/**
 * Handles LTI 1.3 deep linking launches.
 *
 * There are 2 pathways through this page:
 * 1. When first making a deep linking launch from the platform. The launch data is cached at this point, pending user
 * authentication, and the page is set such that the post-authentication redirect will return here.
 * 2. The post-authentication redirect. The launch data is fetched from the session launch cache, and the resource
 * selection view is rendered.
