In this world, kill the ender dragon, then take the teleporter, and press skip to skip the credits
Go up the ladder in the back, from there, get the ender pearl from the chest and throw these somewhere downstairs. You will teleport to the location where the pearl will land. This will most likely be 100 meter or more away. (the platform is about 80 meters high, and you will most likely throw 20+ meters away.) If it still doesn't unlock, use the higher platform or make sure that you are hosting the world on the device you want to unlock it on.
