Add keyframe to event track via Python?

so far I can use SequencerTools.create_quick_binding and create_event to create the event, but how do I add the event to the track(section) with Python? I searched the documentation but can’t find anything. Is this something you can’t do with Python?

I got it… you can get channel from section and add event to the channel.
I wish there can be some examples in the doc, sometimes it is hard to get things together…
