The recap tells the brand that its product reached your moment and what your guests thought. It is not a content request, and it is not a check on you.
The recap opens after your event. It has two short parts: questions first, then photos.
On onbrand, the recap screen is called "Verifications" and the button says "Add photos". Some emails also call the recap "verification". Connecting your social accounts is a different step. It is not part of the recap.
