Now I split the original RegenerateParticipants function into two separate functions: UpdateExistingParticipants and AddNewParticipants. The first one updates information about existing participants, while the second one adds new participants. Now RegenerateParticipants calls these two functions sequentially to update the participants list. This improves the code structure, making it more understandable and modular.
