-- Use one of the following lenses to modify other fields as desired:
--
-- * 'estPipelineName' - The name of the pipeline in which you want to enable the flow of artifacts from one stage to another.
--
-- * 'estStageName' - The name of the stage where you want to enable the transition of artifacts, either into the stage (inbound) or from that stage to the next stage (outbound).
--
-- * 'estTransitionType' - Specifies whether artifacts will be allowed to enter the stage and be processed by the actions in that stage (inbound) or whether already-processed artifacts will be allowed to transition to the next stage (outbound).
