Everything currently in the code is fine, but on the "You've already entered this giveaway!" message there is a "Leave Giveaway" button that lets you leave the giveaway if you already entered it. But the problem is when I press the "Leave Giveaway" button It does not update the 🎉 button label correctly, I've tried many thing. Does anybody know a fix?
class GiveawayView(discord.ui.View):

super().__init__(timeout=None)

await interaction.response.edit_message(view=leave_view)
await interaction.followup.send("🎉 You have left the giveaway!", ephemeral=True)
async def count_user_messages_today(self, channel: discord.TextChannel, user: discord.Member):
count = 0
today = datetime.datetime.now().replace(hour=0, minute=0, second=0, microsecond=0)

count += 1
return count
I expected it to just remove me from the label but nothing happened when I press the button. I am also not getting any error.
In this line of code you are changing the button's label
self.children[0].label = str(len(self.participants))
However, you need to bear in mind that this operation only affects the instance of GiveawayView stored in your bot's memory. For this change to take effect in the Discord message, you need to synchronise the view, which you can do by editing the Discord message.
self.children[0].label = str(len(self.participants))
leave_button = discord.ui.Button(label="Leave Giveaway", style=discord.ButtonStyle.red, disabled=True)
leave_view = discord.ui.View(timeout=0)
leave_view.add_item(leave_button)
await interaction.response.edit_message(view=leave_view)
await interaction.followup.send("🎉 You have left the giveaway!", ephemeral=True)
# updating view in discord side
await interaction.edit_original_response(view=self)
