Help needed with a collect and drop procedure

Hello folks,

I'm currently working on a new mod named "ProgrammingCraft". In this mod, the player has a custom chicken which is a robot entity with a robot texture. In my new mod, the player can program this chicken with new custom in game blocks. I made procedures for every block or for two blocks at the same time, but now I need help with a collect item and a give out a item procedure for the collect item block and for the give out item block. I don't want to make it with custom procedures, I want to do it with vanilla MCreator procedures. But I don't know how I should do this. Who can help me with that?

Greetings,

Atten007 :)
