From what I can gather, it's currently not possible to click a specific part of an AnnotatedString.

Assume we have a String like "This is a string where [a]this part[/a] is clickable.", and let's say we later build an AnnotatedString like this:

buildAnnotatedString {
  append(textBeforeLink) // textBeforeLink = "This is a string where "
  pushStringAnnotation(tag = highlightedTextTag, annotation = linkText) // linkText = "this part"
  withStyle(/*some style*/) {
    append(linkText)
  }
  pop()
  append(textAfterLink) // textAfterLink = " is clickable."
}

In a UI test, I want to click the text "this part". I think it's currently only possible using performTouchInput() and then clicking an area of the string, but that sounds really flaky to me:

onNode(hasText(linkText, substring = true)).performTouchInput {
  click(position = center) // 'position' is really hard to know, and the layout can change depending on the string input.
}

Since we're already providing a tag to the part we're interested in (via pushStringAnnotation()), it would be great to be able to do something like:

onNodeWithText(fullTextHere).performClick(annotationTag = tag)

In Espresso, this was easy enough by implementing a custom ViewAction that would find the spans in the current TextView's text, but it appears we're missing a similar functionality for Compose.
