Can't gain access to the UITextView in the message bubble to handle delegate methods

I have a custom URL scheme that I'd like to handle using the UITextViewDelegate (func textView(UITextView, shouldInteractWith: URL, in: NSRange, interaction: UITextItemInteraction)) methods. Since these are private methods, what would be the best way to solve this problem?

Start by tracing the message bubble's UITextView and the named UITextViewDelegate callbacks, especially shouldInteractWith:in:interaction:. Determine whether the framework exposes a supported way to receive custom URL interactions without relying on private methods; done means the approach is documented and can handle the requested custom URL scheme.
