How to get message reactions updates using node-telegram-bot-api

Question

I wanna make a telegram bot game where bot send a message to group then other members can make reactions on this message. Then I enlist those members data and start the game for those members only.

How can I achive this functionality?

I tried

bot.on('message', async (msg) => {
 const updates = await bot.getUpdates()
 updates.forEach(async (update) => {
 console.log(update)
 })
})

But using this code I didn't avail to get reaction updates for messages.

At first, it is important to explicitly mention the "message_reaction" update type in the allowed_updates for the bot.

const bot = new TelegramBot(token, {
 polling: {
 params: {
 allowed_updates: ["message", "message_reaction"],
 }
 }
});

Now you can listen to changes in message reaction as follows:

bot.on("message_reaction", (reaction) => {
 // `reaction` is of type MessageReactionUpdated (https://core.telegram.org/bots/api#messagereactionupdated)
 // `reaction.user` will be the user who changed the reaction
 // `reaction.chat` will be the chat on which the message to which the reaction is updated exist
});

Make sure to check the official documentation for detailed info on different properties available and customize your bot.

• FliegendeWurst: Do you know how to get the message content based on the reaction event?
• undefined: I have tried exactly that but the callback is never called. Do you have an idea? Do I have to enable something else?
