#Advancement calls a function

Make an advancement that only has a tick requirement and a function as a reward. This function only needs this command: worldborder add <distance that gets added> <time of expansion> and that's it.
add a ticket loop, check with execute if entity for a player without the "alreadyjoined" tag and then expand the worldborder, then add the "alreadyjoined" tag to them
