discord.js how to find role by name

I'm trying to make a sipmle registration function, but I can't figure out what is the problem. This is the code:

fasz.on('messageReactionAdd', async (msg, guild,  reaction, user) =>{
    let registered = msg.guild.roles.find(role => role.name === "Regisztrált");
    if(reaction.message.partial) await reaction.message.fetch();
    if(reaction.partial) await reaction.fetch();
    if(user.bot) return;
    if(!reaction.message.guild) return;
    if(reaction.message.channel.id === '718990681745522728'){
        if(reaction.emoji.name === '👌'){
            await reaction.message.guild.members.cache.get(user.id).roles.add(registered)
            return user.send('Sikeres regisztráció! Üdvözlünk a szerveren!')

        }
    }
})

And this is the error message is get:

C:\Users\god\Documents\GitHub\discord.js\main.js:74
    let registered = msg.guild.roles.find(role => role.name === "Regisztrált");
                               ^

You can get a role by it's name like this:

const role = reaction.message.guild.roles.cache.find(r => r.name === 'Yor role name');

After getting the role you can get the user and assign the role:

const { guild } = reaction.message

const member = guild.members.cache.find(member => member.id === user.id);

member.roles.add(role);

Like I mentioned in the comment, the Client#messageReactionAdd event only emits two variables. That means you cannot arbitrarily use four variables to your liking to assign it.

Code:

client.on('messageReactionAdd', async (reaction, user) => { //basically changed four to two variables
    //replaced msg.guild.roles.find() with reaction.message.guild.roles.find()
    let registered = reaction.message.guild.roles.find(role => role.name === "Regisztrált");
    if (reaction.message.partial) await reaction.message.fetch();
    if (reaction.partial) await reaction.fetch();
    if (user.bot) return;
    if (!reaction.message.guild) return;
    if (reaction.message.channel.id === '718990681745522728') {
        if (reaction.emoji.name === '👌') {
            await reaction.message.guild.members.cache.get(user.id).roles.add(registered)
            return user.send('Sikeres regisztráció! Üdvözlünk a szerveren!')
        }
    }
});
