It is successfull. The above script is written to just trigger all 4 pipeline jobs in only 1 single pipeline. But what stage can be added next so that, this single pipeline waits for the other pipeline jobs selected to complete the run and show the output whether all the selected pipelines are successful or failed with what error and which job. Please provide that stage
