When using a ClickableText (with say an annotated string) and you want to handle clicks only on a certain portion of the string, you cannot easily reason about and write tests for the click handler callback.

For example, given a clickable text like this:

ClickableText(text = myAnnotatedString, 
    modifier = Modifier.clearAndSetSemantics { contentDescription = "My String" },
    onClick = { charOffset ->
        if (charOffset in (5..10)) {
            mySubstringCallback()
        }
    }
)

This is a contrived example, but it's useful to demonstrate the problem. When writing tests (particularly an integration or end-to-end test), it's very difficult to test the click functionality on the above:

val myNode = composeTestRule.onNodeWithContentDescription("My String")

//This won't really do anything useful, since I can't specify WHERE to click.
myNode.performClick() 

// Our only choice to use touch input
myNode.performTouchInput {
    //Oh boy, this is going to be challenging.
    // I'm going to have to write my own algorithm to calculate
    // a touch point that falls within the annotated string at a 
    // position that corresponds to the range of characters between offset 5 and 10
      
    ...
}

It would be useful if there was an action that could do this for me. Something like:

myNode.performTextClick(offset = 7)
