Custom Events: Documentation?

I am manually sending certain events to Sentry using client.capture_event(<event_dict>). Sentry is receiving the events fine and I’ve managed to figure out many of the valid keys in the event dictionary object. However, I’d like to have more control over things like how the issue title and subtitle are displayed. Is there somewhere that I can find detailed documentation of the Event dictionary keys that are available and how they relate to how the Issue is rendered in Sentry?

You probably found this months ago, but the various sdk docs include more info. Here’s the event interface for javascript.
