Assistance Needed

[Jordaar]

I was wondering what does the "identifier": "", in config.json means

and also can you guide me how i can set custom status of the bot if possible?

Sorry for the late reply, totally missed that.
The identifier field will add a prefix in front of the name of a user. You can use that to identify each guild with custom strings like emotes.
For custom status, see here.
TLDR:

bot.editStatus('dnd', {
    name: 'relying messages',
    type: 3,
})
