A bot that deletes all messages except for messeges saying "potato" - discord

Question

I have been trying to make a bot that only allows the messages saying, "potato" and deletes all other messages with different content. (I am very new to this stuff.)
Here is the code I've tried so far, created by a user here:
client.on("message", (message) => {
if(message.content != "potato") return message.delete()
});
When I input it into the code, I get an indent error and a semi-colon error. When I auto fix them, I get this code:
client.on("message", (message) => {
if(message.content != "potato") return message.delete();
});
The terminal repeats back the messages in the server (has no roles or perms), but doesn't delete them in discord if they aren't "potato". The bot has Admin perm.
Any edits or suggestions? (I do have a linter, not sure if relevant.)
Thanks, PM
Rest of code:
const Discord = require('discord.js');
const client = new Discord.Client();
client.once('ready', () => {
console.log('Ready!');
});
client.login('TOKEN');
client.on("message", (message) => {
if(message.content !== "potato") return message.delete();
});

You need to put await before the message.delete() otherwise it won't work.
It's also better for code readability to put client.login at the bottom of the code.
Your code should look like this:
const Discord = require('discord.js');
const client = new Discord.Client();
client.once('ready', () => {
console.log('Ready!');
});
client.on("message", async (message) => {
if(message.content !== "potato") {return await message.delete();}
});
client.login('TOKEN');
