How can I instance a block into a mesh in Blender?

Question

In Blender, I have 2 objects:

1. One is a mesh which is a huge chunk of gold blocks.
2. Other is a singular block.

How can I instance the singular block to form the gold chunk mesh so that I could do procedural animation (I'm new to geometry nodes).

Here’s the Blend file if you want:
