Sudo tx with subxt

Question

I'm writing a script with subxt. How can I wrap a set_code tx in a sudo_unchecked_weight tx?

Current code:

    let sudo_set_code: Payload<SetCode>  = nodetemplate::tx().system().set_code(code);
    let weight = Weight {
        ref_time: 0,
        proof_size: 0,
    };
    let sudo_tx = nodetemplate::tx().sudo().sudo_unchecked_weight(sudo_set_code, weight);

Traceback:

Solved it:

  let call = nodetemplate::runtime_types::node_template_runtime::RuntimeCall::System(
        SystemCall::set_code {
            code: wasm_binary.expect("could not decode wasm binary").into(),
        },
 let sudo_tx = nodetemplate::tx()
        .sudo()
        .sudo_unchecked_weight(call, weight);
