• After finding the registration, Anna needs an overview of it. The overview needs to list the relevant information like "additional fields" and also include the payment status
• In case any information is incorrect, Anna needs a way to correct it
• Anna needs to add a note that the participant has arrived, and get back ready for the next participant
