UI should open up a dialog / mini window to display events related to a chart release. It might be even nice to have them available if user clicks on the chart release name with some other information which is already available like used ports etc - so it gives a nice summary of the chart release.
For middleware please use, 'chart.release.events' endpoint to retrieve these events. To clarify, they are not middleware events. If there are any concerns, please let me know. Thank you
