Limit reactions to one per message

discord.js :[email protected] Node: v20.2.0 I'm trying to make a poll bot based on reactions and I'm trying to limit reactions so that each user can only be reacted to one emoji at a time. Currently I have a system that checks if a user is already reacted and if so, removes and new reactions until they remove their original reaction but I'm wondering if a system that would remove the old reaction is instead possible? This is the current system I have for the limiting.

interaction.client.on("messageReactionAdd", async (reaction, user) => {
      //Check that the reaction is not a partial
      if (reaction.message.partial) await reaction.message.fetch();
      if (reaction.partial) await reaction.fetch();

      /*Check if:
      the reactor is not a bot,
      if the reaction is in a DM,
      if the message reacted to is the poll for this interaction,
      if the poll has ended and return if any are true */
      if (
        user.bot ||
        !reaction.message.guild ||
        pollMessage.id != reaction.message.id ||
        timedOut
      )
        return;

      //No new reactions emojis can be added
      if (!reactionEmojis.includes(reaction._emoji.toString())) {
        reaction.users.remove(user.id).catch(console.error);
        return;
      }

      const { message } = reaction;
      let member = reaction.message.guild.members.cache.get(user.id);

      //Limit reactions to member if need be
      if (roleID != null) {
        if (!member.roles.cache.has(roleID.value)) {
          reaction.users.remove(user.id).catch(console.error);
          return;
        }
      }

      if (!reactionCount.get(message))
        reactionCount.set(message, new Collection());
      const userCount = reactionCount.get(message);
      userCount.set(user, (userCount.get(user) || 0) + 1);

      if (userCount.get(user) > 1) {
        reaction.users.remove(user);
        return;
      }

        pollMessage,

• What's your exact discord.js npm list discord.js and node node -v version? • Post the full error stack trace, not just the top part! • Show your code! • Explain what exactly your issue is. • Not a discord.js issue? Check out #useful-servers.

Forgot to say but reactionCount is a Collection!
