How do i make a discord bot that simply gives me a role when i type a certain phrase in Javascript?

Question

I've done tons and tons of searches but they're all super complex codes such as, when i say "!Role (role)" then it gives me the role i specified. However, what i am looking for is something much simpler like if i were to say "Hello", then the bot would give me the role that's in the code.

I also tried a lot of the complex ones but most of them used the "addRole" function but the output didn't like it

Do you think you can help me with this?

Discord JS V12:

client.on("message", (message) => {
    // Checking if the message equals to "hello".
    // Since we use .toLowerCase() which converts any uppercase letter to lowercase, HeLLo will result in hello.
    if (message.content.toLowerCase() == "hello") {
        // Trying to find the role by ID.
        const Role = message.guild.roles.cache.get("RoleID");
        // Checking if the role exists.
        if (!Role) { // The role doesn't exist.
            message.channel.send(`I'm sorry, the role doesn't exist.`);
        } else { // The role exists.
            // Adding the role to the user.
            message.member.roles.add(Role).catch((error) => {console.error(error)});
            message.channel.send(`You received the role ${Role.name}.`);
        };
    }
});
