Request: Add information on how to call constructOutboxProof(uint64 size, uint64 leaf)

I'm launching an orbit node and I want to add a function that executes a message from L2 -> L1. So the user needs to call the executeTransaction in the Outbox contract on layer 1 and pass it the proof and all the other parameters.

How do I develop this in my front-end? More specifically:

• What does the size and the leaf parameters refer to on the constructOutboxProof(uint64 size, uint64 leaf)? How do I calculate this values? Is it from this equation position = (level << 192) + leaf = (0 << 192) + leaf = leaf? How do I calculate the "level"?
• I've found this example for outbox execution but I can't configure the address of the outbox, which is necessary for my orbit L3.
