Discord.js creating a private voice channel and role - discord.js

Question

I am trying to make a discord bot with Discord.js, that can create a private channel and a new role and assign that role to the channel. So any users with the new role can access the channel.
The following code, creates a channel from the name i give it through 'eventName' it also creates a role of the same name.
But how do i make the voice channel private, set a role to exclusively access it and set some permissions to the new role?
function addChannel(message,args,eventName){
var server = message.guild;
var permsName = eventName+"-"+message.author.username;
message.guild.createRole({
//data: {
name: permsName,
permissions: []
//},
//reason: 'new Event'
}).then(role => {
message.member.addRole(role,permsName)
.catch(error => client.catch(error))
}).catch(error => client.catch(error))
server.createChannel(eventName, 'voice').then( // Create the actual voice channel.
(chan) => {
chan.setParent("427382662240534535").then( // Move the voice channel to the current message's parent category.
(chan2) => {
console.log("stage 3");
console.log(chan2);
//console.log(`Set the category of ${chan2.name} to ${chan2.parent.name}`);
chan2.overwritePermissions(message.guild.roles.find('name', '#everyone'), { 'CREATE_INSTANT_INVITE' : false }); // Give the channel some standard permissions.
chan2.overwritePermissions(message.guild.roles.find('name', permsName), {
'CREATE_INSTANT_INVITE' : false, 'ADD_REACTIONS': true,
'READ_MESSAGES': true, 'SEND_MESSAGES': true,
'SEND_TTS_MESSAGES': true, 'MANAGE_MESSAGES': true,
'EMBED_LINKS': true, 'ATTACH_FILES': true,
'READ_MESSAGE_HISTORY': true, 'MENTION_EVERYONE': true,
'EXTERNAL_EMOJIS': true, 'CONNECT': true,
'SPEAK': true
});
console.log("stage 4");
}
).catch(console.error);
}
).catch(console.error);
return '```Added```';
}

Theres two problems here, for one you are using a lot of unnessecary permissions here, for Voice obviously reactions reading and sending messages etc are not important, important are only VIEW_CHANNEL, SPEAK, CONNECT, and CREATE_INSTANT_INVITE, and you have to explicitely forbid everyone for a standard discord server setup since everyone usually has these rights Serverwide unless locally overwritten.
So what you want for your overwrite permissions is:
chan2.overwritePermissions(message.guild.roles.find('name', '#everyone'), { // Disallow Everyone to see, join, invite, or speak
'CREATE_INSTANT_INVITE' : false, 'VIEW_CHANNEL': false,
'CONNECT': false, 'SPEAK': false
});
chan2.overwritePermissions(message.guild.roles.find('name', permsName), {//Explicitely allow the role to see, join and speak
'VIEW_CHANNEL': true, 'CONNECT': true, 'SPEAK': true,
});
Note that you do not have to explicitely disallow CREATE_INSTANT_INVITE since that is inherited from everyone if not explicitely changed.
