add/ editing/ delete subtitle with api jsx

I'm trying to edit the timeline subtitles in Premiere Pro, and I'd like to be able to add, modify, and delete certain subtitle segments using the API.

However, I can't seem to find the corresponding interface. Are there any documents or tips on how to do this? Thank you.

You're not missing much; while you can import an .srt file using standard file import mechanisms, there are no APIs around modifying subtitle segments. 

You're not the only developer who wants to do that; once UXP is closer to parity with the functionality provided by CEP+ExtendScript, we plan to expose more APIs around captions and subtitling.
