message reaction could not get user's selected reaction from cache after rebooting bot

[lokyse]

Which package is this bug report for?

discord.js

Issue description

User choose some reaction in the message, so the reaction records the user's info, and we could use messageReaction.users.remove(user.id) method to remove this user(who has selected the reaction) by id in the reaction that mean user unselect the reaction.

The issue it that if I reboot bot program , The program could fetch message and reactions belong to message at 'messageReactionAdd' event handler. But the reaction don't have those user who has selected it before reboot bot program.
I see MessageReaction.users.cache.get(user.id) method don't give me the user as expected instead of 'undefine' value.

Code sample

client.on("messageReactionAdd", async (reaction, user) => {
            if (user.id === client.user.id) return;

            if (reaction.partial) {
                  // If the message this reaction belongs to was removed, the fetching might result in an API error which should be handled
                  try {
                        await reaction.fetch();
                  } catch (error) {
                        console.error(
                              "Something went wrong when fetching the message:",
                              error
                        );
                        return;
                  }
            }

//   omit  code ....
// ....



  const userReactions =
                                          reaction.message.reactions.cache.filter(
                                                (reaction) =>
                                                      reaction.emoji.name ==
                                                            selected.choiceEmoji &&
                                                      reaction.message.id ==
                                                            selected.pollId
                                          );


                                    userReactions.forEach((e) => {
                                          // has value
                                          console.log(e.emoji.name, e.count);
        
                                          // not work here!  got 'undefine' 
                                          e.users.cache.get(user.id)
 
                                         // e.users.remove(user.id);
                                    });

Seems like you don't know this exists: ReactionUserManager#fetch()

Seems like you don't know this exists: ReactionUserManager#fetch()

client.on("messageReactionAdd", async (reaction, user) => {
            if (user.id === client.user.id) return;
            // I add user.fetch here,   right?
            await reaction.users.fetch();
            if (reaction.partial) {

But It still not work, 'e.users.cache.get(user.id)' give me undefine

I would say that ReactionUserManager#fetch() system through the current version of discord.js should work.
Check discord.js logs for this question for better approval and understanding.
