Making a Block that removes itself after 5 seconds

Hello again Modders of Forge!

I am trying to make a Block that will remove itself from the world after 5 seconds of being placed. I have tried to use Thread.sleep and wait() in the onBlockPlaced method to no avail. I also tried to use an IScheduledTickHandler. If you have any idea on how to do this please post below. If you need any code snippets I will gladly post if you ask.

Minecraft is single threaded, wait and thread.sleep are only going to pause the whole game.

You need to use the onUpdateTick method of the block and world.scheduleBlockUpdate(...) method.
