Help me with My giveaway command

[signal sentinel]

the button one can be done easily. you can subclass a view (or just a button) and inside the class you can have a list of user ids that have entered the giveaway

then for the button callback, you check if the interaction user id is in the list. depending on the result you either add or remove the user id from the list and send a message in response to let the user know

also providing code would be very helpful

i just explained to you how you can do it
