How to update user permission discord js

So, I want to update a permission for some users. First, I tried to create a text channel and overwrite a user Permission. Then I do a for loop to update the permission, but I dont know how. Things I've tried to update the permission : 

channel.overwritePermissions({
    permissionOverwrites: [
        {
            id: guild.id,
            deny: ['VIEW_CHANNEL'],
        },
        {
            id: playerData[i],
            allow: ['VIEW_CHANNEL'],
        },
    ],
});
//it said channel not defined?

message.guild.channels.cache.find('🐺werewolves').overwritePermissions({
        permissionOverwrites: [
            {
            id: playerData[i],
            allow:['VIEW_CHANNEL'],
            }
        ]
    })
//it said : fn is not a function

I've I have seen this solution and read the documentation, but the instruction isn't clear.

PS : The permission update must be a loop because the number of users who get the permission always changing.

Regarding first codeblock

channel is not defined, because it's not defined. You cannot use variables without defining them, that's how JavaScript works. To solve it, you would have to define it using for example const channel = ..., or access it from other variables you have, just like you are trying to use find in your second codeblock - you access it from message, as you're most likely in the message event.

Regarding second codeblock

This is not a proper way to use find, neither in old - removed in your version - way, nor the new way. The old way was to do find(property, value), to which you wouldn't provide a value ('🐺werewolves' would be treated as property you're trying to search by). New way you have to use, allows way more flexibility by requiring to pass it a function, just like in the example for the method. Since what you passed was a string and not a function, internal code throws an error fn is not a function.

For your example above, correct way to use that find would be

message.guild.channels.cache.find(channel => channel.name === '🐺werewolves');

Additionally, note that ideally you shouldn't try to call any methods on that directly, as in case when no channel with that name would be found, your code will throw an error. Snippet below should avoid that possibility.

const channel = message.guild.channels.cache.find(channel => channel.name === '🐺werewolves');
if (channel) channel.overwritePermissions(...)
