Using Node.js 16.9.0

Hi All!

So in my discord server I have a few friends who like to "Sleep Call", but need to be disconnected a few hours after they fall asleep by a moderator. I would like to add a command to my discord bot that functions like ".sleepcall 3h", and then in 3 hours they would be disconnected from the VC they are in. My current thought is to create a entry in my sql db with the disconnect time (current time + desired wait time), and then have a loop run every minute to see if anyone needs to be disconnected. Someone mentioned to me that there is a way to do that with loops instead in JS, and I need a bit of direction to get started. I think I'll be able to do all the support code, but I am a bit lost on how to make the timer. I am proficient in c++, but have never dabbled into asynchronous languages before.

How would I make a function that, after called, would wait 1 hour (for example) and then call another function WHILE also being asynchronous that allows for multiple timers to be going at once?

My sudocode:

//userID = 8 digit integer
//timeout = time until disconnect in seconds

function disconnect (userID, timeout){
   while (timeout >0){
     timeout-1 second
     wait 1 second
   }
   if (timeout == 0){
     disconnect(userID)
   }
}

I would need multiple instances of the countdown function to be able to run at the same time to allow for multiple users to use the bot
