What is the issue with handling multiple post reactions on the same channel button in Discordjs v14?

edit

In Discordjs v14, handling multiple post reactions on the same channel button can be an issue due to changes in the way the library handles events. Specifically, the new raw event does not provide information about individual reactions on a message, but instead provides an array of all reactions on the message at the time the event was fired. This means that if multiple users react to the same message within a short period of time, it may be difficult to determine which reaction came from which user.

As a workaround, developers may need to use additional data structures or caching to keep track of which users have reacted to a message and what their reactions were. They may also need to implement more complex logic for handling multiple reactions and ensuring that each user's reaction is handled appropriately.
