HOW TO IMPLEMTENT A A GUI BUTTON THAT AFFECTS A BLOCK ENTITY MINECRAFT 1.20.1

[DukeLowDX]

Hello, guys!

I'm creating a mod that includes a machine. This machine has 4 slots: 2 input slots and 2 output slots.

For this machine to work, it needs two things: 2 valid items in the input slots, and it requires that the player clicks on the "uncraft" button in the center of the GUI. Then the progress will start.

However, I'm not able to make the block entity understand that the button was clicked on the client side.

Does anybody know how to implement a GUI button that updates a block entity variable?
This is my project: https://github.com/jujulioed/Dukas_Utilities_Mod (in this version, the button interaction was not implemented yet.)

You need to send a network message to the server, saying which button in which block got pressed.

There is no real standard for this, you will need to look at other mods if you want example code, e.g.
