Onboarding - how to prioritize key actions

Question

I would like to implement the Quickstart experience in my application as described here: https://material.google.com/growth-communications/onboarding.html#onboarding-quickstart

In particular, I would like to highlight the priority for my key action - the buttons with the floating action, as shown in the following screenshot: https://material-design.storage.googleapis.com/publish/material_v_8/material_ext_publish/0B7WCemMG6e0VYmdoeTFfMTZPWVk/patternoDoDome

Are there any examples that implement this behavior? Or at least some kind of vector graphics that I can use as a background? Unfortunately, I could not find anything in this direction except this single screen shot.

More generally, does Google provide some kind of kitchen where they show how to implement their own recommendations?
