storing and recalling custom Player's data

[spiritfilled]

hiii :3
i just want to know, how to store entity data at 1.16 to 1.17

ive been doing this before at 1.12:

player.getEntityData().setByte("om_orientation", (byte) 0);

i don't know how it is in 1.17

i saw something on Player.Class, it goes like this...

this.getEntityData().set(DATA_PLAYER_ABSORPTION_ID, p_36396_);

but DATA_PLAYER_ABSORPTION_ID, is EntityDataAccessor <T> (dunno what that is)

   private static final EntityDataAccessor<Float> DATA_PLAYER_ABSORPTION_ID = SynchedEntityData.defineId(Player.class, EntityDataSerializers.FLOAT);

im doing a thing where i store tick counts on each player, i dunno if there is a simpler way of doing it or whatsoever

can anyone pls help. thanks :3
