how to call coroutine functions within the co_composed?

[zhllxt]

asio::awaitable<bool> do_check()
{
       co_return true;
}

template <typename CompletionToken>
auto async_work(asio::ip::tcp::socket& socket, CompletionToken&& token)
{
return asio::async_initiate<CompletionToken, void(std::error_code)>(
    asio::experimental::co_composed<void(std::error_code)>(
        [](auto state, tcp::socket& socket) -> void
        {
            // ...

            bool result = co_await do_check(); // compile error

            // ...

        }, socket),
    token, std::ref(socket));
}
