I using an iterator to create multiple pieces of content using Claude. I am getting rate limited. I am using the data forwarder as instructed since the iterator cannot have a delay step. But having the delay step in the forwarded workflow from an iterator doesn't work to get around the rate limit. All it does is delay the start of the forwarded workflow but it doesn't space out each iteration. If I want to space out the time between iterations, how is that done?
