How to await for async stuff within a moc.perform block

I want to implement this pattern in my app:

let moc = ...newBackgroundContext()

try await moc.perform {
  // test for existence of a specific object in the moc

  if !objectExists {
    let apiObject = await api.fetchObjectFromNetwork()
    // create managed object from apiObject
    try moc.save()
  }
}

Unfortunately, I am unable to await my network call because the moc.perform block is not async.

So far, I've come up with this solution:

let moc = ...newBackgroundContext()

try await moc.perform {
  // test for existence of a specific object in the moc

  if !objectExists {
    Task {
      let apiObject = await api.fetchObjectFromNetwork()

      try await moc.perform {
        // create managed object from apiObject
        try moc.save()
      }
    }
  }
}

But it doesn't feel quite right.

What do you think? Am I on the right track, or am I introducing unneeded complexity?
