How to apply an inverted mask to a Label?

Similar to the masking shown in this documentation, how would I created an inverted mask to the text from a Label?

UiFx Bundle has this feature but for Canvas, if you dont want to wait for ui toolkit to catch up, then you can request @ChocDino for this, He is the best when it comes to such visual effects and filters and already provided so many features on my own request, so in short a happy customer

@jGate99 I am currently not looking for uGUI effects.
