Playing ads by using IMA SDK in Roku SG

I want playing ads by using IMA SDK.

After some R&D I found and downloaded Roku SG “IMA SDK Sample apps” from “https://support.google.com/dfp_premium/answer/7298842?hl=en”.

The sample app is not have briefly described documentation.

IMA SDK is a separate product by Google and the question best answered by them.
