Discord.js How to access the message using messageReactionAdd – Javascript

I currently have this function in my bot that triggers every time a message is reacted to:

client.on('messageReactionAdd', (reaction, user) => {
    if(reaction.emoji.id === "1014887969808711800") {
        if (user.username !== 'IteroBetBot') {
            console.log('Fnatic');
            voterArray1.push(user.username);
        }
    } else if (reaction.emoji.id === "1065285604578959430") {
        if (user.username !== 'IteroBetBot') {
            console.log('Koi');
            voterArray2.push(user.username);
        }
    }
     else if (reaction.emoji.name === '🚫') {
         console.log('Found it');
         let finalString1 = '';
         let finalString2 = '';
         voterArray1.forEach(element => {
             finalString1 += element + " "
         });
         voterArray2.forEach(element => {
            finalString2 += element + " "
        });
        finalString1 += ' voted for Fnatic';
        finalString2 += ' voted for Koi';
        client.channels.cache.get('1077613044563202058').send(finalString1);
        client.channels.cache.get('1077613044563202058').send(finalString2);
    }
});

I need to be able to access the message that was reacted to in order to check if the stop emoji already exists on the message.

How could I access the message messageReactionAdd was called on?
