Functions are showing up

I am trying to make a datapack for version 1.21 but a couple of the functions are not showing in game. There are 2 files that are giving me trouble They are as follows: kick_all.mcfunction execute as @a run kick @s start_session say The AFK Session is starting. It will last approximetly 11 minutes, and will simulate 8 hours. say After 20 minutes EVERYONE will be kicked to conserve resources. tick sprint 28800s schedule function voteafk:warn_kick_all 900s And the voteafk:warn_kick_all function does appear ingame. Can anyone spot anything wrong here?
