How to use startSpan with generator functions

[PRESIDENT810]

Our project uses redux-saga and we use generator functions very heavily. We are using @sentry/react v7 which works fine because startTransaction API because it returns a transaction object and doesn't use callback. However, after we upgrade it to v8, startTransaction is gone and there's only startSpan where it takes a callback in which you make changes to the span object.

I find our code is is not compatible with this API at all. For example, we use Sentry to trace a network request in a generator function which looks like this:

function* sendRequestEffect() {
    const transaction = Sentry.startTransaction({/*...*/});
    const span = transaction.startChild({/*...*/});
    // Network stuff...
    const response = yield call(sendRequest);
    if (response.status == 400) {
       span.setStatus(SpanStatus.Ok);
    }
}

With v8, it has to be

function* sendRequestEffect() {
    yield Sentry.startSpan({/*...*/}, function* (span) {
        // Network stuff...
        const response = yield call(sendRequest);
        if (response.status == 400) {
           span.setStatus(SpanStatus.Ok);
        }
    });
}

I assume it wouldn't work?

Is there any way to make use of the new tracing API with generator functions? If not, can we have a tracing API that doesn't require a callback function? Otherwise we can never upgrade Sentry beyond v8
