hello I would like help for the creation of a new bee that does not exist in the base mod,
thanking you in advance!!!

What bees do you want to create?

I would like to add various bees not included in the mode such as a grass bee, a guardian heart and others

The quarry bee can make grass blocks already
Guardian hearts sound like it's a drop so that's covered by the WannaBee

heart of the sea I use as a crafting component in the omega upgrades and I'm not really keen on adding a bee for it
you can always add one yourself or modify the output of an existing bee

as for grass it might be interesting to look into a bee that clears/harvests grass and flowers near the hive but it would need to be accompanied by a bee that bonemeals around the hive too
