hello,

prompt and have the opportunity to insert into the subtitles link?

I think you want to ask the user to provide subtitle link and then load it?
Well, it doesn't have this feature, but it should be possible to have a prompt external to videojs but have some logic to reinitialize the videojs player with updated subtitle link inserted into the plugin config.

highlight the subtitle text with the cursor like a regular text

You can do it by removing pointer-events: none; in .vjs-ass class here or just overwrite the style with

.vjs-ass {
  pointer-event: auto
}

Seems like I've misunderstood what you meant by subtitles link
but it looks like you've already got your answer at Arnavion/libjass#82.
