How to make foreground widget to bubble touch input to background widget

I have a Foreground widget that only has a Canvas Panel that covers the entire screen and it has Visibility set to Visible. I override the Touch Started function and set the result to Unhandled. The Background widget just has a button and it’s behind the Foreground widget. I wanted to be able to trigger the Touch Started function on the Foreground widget but also bubble that to the Background widget so it still hits the button, but the Unhandled didn’t seem to help with that. The use case for this is to have an invisible widget layer on top of everything that processes touch inputs to do some custom logic, but still relays all of the inputs to what is behind it. Is there any way to accomplish that?

Thank you!
