How do I get every sprites from the discord ?

All the tutos are 3 years old, and they talk about all the sprites being in a specific channel in the discord, but I can't find anything in it other than the games. There are monthly Sprite packs in another channel, but I feel like it is only the new ones. I think I saw somewhere that the game downloads automatically all the sprites, so I don't need to do it manually but I really feel like I am missing a lot of sprites. Please Help and Thank you in advance!!
