Error to retrieve data from "raw" event

Question

Well, I have a bot with this event:

Bot.on('raw', async (event) => {

  if (event.t == "MESSAGE_REACTION_ADD") {

const { d: data } = event;
const user = Bot.users.fetch(data.user_id);
const channel = Bot.channels.cache.get(data.channel_id)
const message = await channel.messages.fetch(data.message_id);

console.log(event.d.emoji.name)
}
});

But I’m making the following mistake:

TypeError: Bot.users.fetch is not a function

This worked on the old BOT. I know there is a specific event for MESSAGE_REACTION_ADD, but it doesn’t work for me.

If you can help me, I’d appreciate it.

the function is for a BOT for Discord
