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.
