turn on Ad timer for the RAF?

How do I turn on the ad countdown timer of a Roku Advertising Framework (RAF) video? i.e. something like “your program will start in 29 seconds”

Has anyone used a countdown timer for their ads?

I can see:
“If the client application has no need for custom UI or user interaction during ad rendering, it is recommended to use the default rendering method showAds()[/url:12uhzn6n]. This method handles rendering and control of interactive and video ads, as well as displaying basic messaging UI (e.g., “Your program will continue after these messages”) and feedback UI (“Ad 1 of 3”).”

But I can find how to change feedback UI.

The solution was in implementing custom ad UI. It requires to do all work manually: create component with video player to show ads and Label above it. Then update Label text during ad playback.
