Transform examples/tokens/custom_fee_royalty.py to be an end to end example

[exploreriii]

Problem

examples/tokens/custom_fee_royalty.py
illustrates locally how to create a custom fee
but it is missing connection to hedera and steps like setting up a client, creating a token, adding the custom fee, and querying token info to see if its correctly set

Solution

Make examples/tokens/custom_fee_royalty.py and end-to-end example, like the majority of our other examples

Alternatives

No response

i am willing to take this up

Greta, @prishajaiswal75
This is a harder one so please do take it step by step and run it at each step
As we are experiencing a bug with our TLS you'll need to explicitly disable it (just when running this locally):
e.g.

def setup_client():
    """Setup Client """
    network = Network(network_name)
    print(f"Connecting to Hedera {network_name} network!")
    client = Client(network)

    # Disable TLS completely
    client.set_transport_security(False)
    client.set_verify_certificates(False)
    # Disable TLS completely

    # Get the operator account from the .env file
    try:
        operator_id = AccountId.from_string(os.getenv('OPERATOR_ID', ''))
        operator_key = PrivateKey.from_string(os.getenv('OPERATOR_KEY', ''))
        # Set the operator (payer) account for the client
        client.set_operator(operator_id, operator_key)
        print(f"Client set up with operator id {client.operator_account_id}")
        return client
    except (TypeError, ValueError):
        print("Error: Please check OPERATOR_ID and OPERATOR_KEY in your .env file.")
        sys.exit(1)

I started implementing the end-to-end custom_fee_royalty example as you suggested and tried running it locally step by step.

While testing on main, I noticed that the SDK imports hiero_sdk_python.hapi.* (in client/client.py), but the src/hiero_sdk_python/hapi/ directory does not exist in the repo after a fresh checkout + submodule init.

This causes a ModuleNotFoundError before the example can run, even with TLS disabled as suggested.

Am I missing a generation step or is hapi expected to come from a submodule / different branch?
I wanted to check before proceeding further with the example implementation.

[exploreriii]

yes, please read CONTRIBUTING.md it will have the generation instructions, we have a file, generate_proto.py

run
uv run python generate_proto.py
from root
