Hi, I'm creating group tracks, tracks, and clips through code. After creating a group (GroupTrack), the timeline does not always update and "know" about changes. So in order to play the timeline with the changes, I have to re-open the "Timeline" window. What is the best way to refresh the timeline through code without using any editor scripts? Say, if I'm constructing the timeline entirely in runtime (outside of the editor) and want to play it back with all the changes immediately. I'm using Unity 2019.1.2f1. Thank you.
