RAF + skippable Ads

Hi. I need an advice.

I need to implement skippable Ads on Roku. I use RAF to render Ads.

According to the documentation, there is a method (setAdExit), which allows to skip Ads using Back button. It marked as deprecated though it currently works.

But I need to implement the "full" version of skippable Ads, including countdown timer and Skip button. 

Does RAF have a built in functionality for this (there is no info in the documentation)?

What other choices I have except RAF?

Thanks.
