Lockdown Channel command and Unlock channel - node.js

Question

It's a strange question about lockdown channel but why this is not working?
This is the script of my lock command msg.channel.guild.roles.everyone if that everyone define as #everyone? I've seen this script in documents of discord permissions. I tried it but it's not working. And there's no error too.
client.on('messageCreate', msg => {
if(msg.content.toLowerCase().startsWith(`${prefix}lock`)){
msg.channel.permissionOverwrites.create(msg.channel.guild.roles.everyone, { SEND_MESSAGES: false });
msg.channel.send('Channel Locked')
}else if(msg.content.toLowerCase().startsWith(`${prefix}unlock`)){
msg.channel.permissionOverwrites.create(msg.channel.guild.roles.everyone, { SEND_MESSAGES: true });
msg.channel.send('Channel Unlocked')
}
});

Answer 1

message.channel.updateOverwrite(message.guild.id, {
SEND_MESSAGES: false
});
Unlocked the channel use
message.channel.updateOverwrite(message.guild.id, {
SEND_MESSAGES: null
});
for example
client.on("message", async message => {
if (message.content.startsWith(prefix + "lock")) {
if (!message.member.hasPermission("MANAGE_CHANNELS")) return;
if (!message.guild.member(client.user).hasPermission("MANAGE_CHANNELS"))
return;
message.channel.updateOverwrite(message.guild.id, {
SEND_MESSAGES: false
});
const lock = new Discord.MessageEmbed()
.setColor("#00000")
.setDescription(
`🔒 | Locked Channel
❯ **Channel Name :** <#${message.channel.id}>
❯ **Locked By :** <#${message.author.id}>
`
)
.setThumbnail(message.author.avatarURL())
.setFooter(`${message.author.tag}`, message.author.avatarURL())
.setTimestamp()
message.chaneel.send(lock);
}
});
This is embed
