I need to determine whether RPCs are enabled in a OCW. I am thinking that I could check rpc_external and/or ws_external in sc_cli::commands::run_cmd but (1) is this the best way and (2) if it is, how do I access it? For the latter, I tried adding sc-cli as a Cargo.toml dependency but it generated a bunch of errors.

lib.rs:

    if sc_cli::commands::run_cmd::rpc_external {
        frame_support::log::info!("RPCs enabled");
    } else {
        frame_support::log::info!("RPC disabled");
    }

Cargo.toml:

sc-cli = { default-features = false, git = "https://github.com/paritytech/substrate.git", branch = "polkadot-v0.9.28"}
