Craftable Spawn Eggs

My first ever Datapack! Featuring a brand new way to craft spawn eggs in your survival world! I'm not fully sure if the recipes will appear in the recipe book, if not then I guess I'll have to make a list of all the recipes!

For the majority of the eggs, to craft them you will need an egg in the middle, a totem of undying in the bottom, and fill the 7 empty remaining slots with an item relating to the mob in question! Though there are some other ways to obtain them! Such as smithing a spawn egg with another object to get a new spawn egg, or using the stonecutter on one, or even smelting a spawn egg! There's even a new advancement for obtaining 1 of each spawn egg!
