(Discord.js) FetchMessages in specific channel

Question

I'm a beginner in bot creation but I have a few code bases. I've created a report command: !report

It works fine, and as soon as there is a report, an embed is created in the report channel, except that I can't add a reaction on it, it adds the reactions on the report command. I know you have to use FetchMessages but I don't understand how it works with the new version (12).

client.on( 'message', message => {
    if(message.content.startsWith("!report")) {
        let messageArray = message.content.split(" ");
        let args = messageArray.slice(1);
        let member = message.mentions.users.first();
        if(!member) return message.channel.send("Cannot find this user.");
        let reason = args.slice(1).join(" ");
        if(!reason) return message.channel.send("The reason for postponement is mandatory!");
        const embed = new MessageEmbed()
            .setAuthor("Mandela Bot", "https://i.ibb.co/wNZW68r/Logo.png")
            .setTitle("Report")
            .setFooter("Reports - Mandela Bot")
            .setColor("0x9500FF")
            .addField("User", (member), true)
            .addField("reason", (reason), true)
            .addField("Reporter", ("<@" + message.member + ">"), true)
            .addField("Delete report", "✅", true)
            .addField("Ban the user", "❌", true)
        client.channels.cache.get("689899680724811886").send(embed)
        const channel = client.channels.cache.get("689899680724811886")
        message.react('✅').then(() => message.react('❌'));
    }
})

I would like to be able to add my 2 reactions on the embed that is sent just before, can you please help me!

You can use promise of sended message for this. Its better then try to fetch message, because all discord actions return a promise . So when you send message, update role, update member you can use .then(data => and data will be message, updated role or updated member.

client.on('message', message => {
    if (message.content.startsWith("!report")) {
        let messageArray = message.content.split(" ");
        let args = messageArray.slice(1);
        let member = message.mentions.users.first();
        if (!member) return message.channel.send("Cannot find this user.");
        let reason = args.slice(1)
            .join(" ");
        if (!reason) return message.channel.send("The reason for postponement is mandatory!");
        const embed = new MessageEmbed()
            .setAuthor("Mandela Bot", "https://i.ibb.co/wNZW68r/Logo.png")
            .setTitle("Report")
            .setFooter("Reports - Mandela Bot")
            .setColor("0x9500FF")
            .addField("User", (member), true)
            .addField("reason", (reason), true)
            .addField("Reporter", ("<@" + message.member + ">"), true)
            .addField("Delete report", "✅", true)
            .addField("Ban the user", "❌", true)
        client.channels.cache.get("689899680724811886")
            .send(embed)
            .then(msg => {
                msg.react('✅')
                    .then(() => msg.react('❌'));
                const filter = (reaction, user) => ['✅', '❌'].includes(reaction.emoji.name)
                msg.awaitReactions(filter, {
                        time: 300000,
                        max: 1
                    })
                    .then(collected => {
                        const reaction = collected.first()
                        if (reaction.emoji.name === '✅') {
                            // Do somthink
                        } else if (reaction.emoji.name === '❌') {
                            // Do somthink
                        }
                    })
                    .catch(collected => {
                        // Do somthink
                    })
            })
    }
})
