Adding Payment and Advertisement to Libgdx Project

I am trying to add my project firebase advertisement, google pay/apple pay and fabric/crashlytics. I followed some links which is in this forum or intel documentation. I kinda lost in these many applications and don’t know where to start.

At first case, I have shown an Action which comes out Right Click MOE module -> Multi - OS Engine Actions and Link third party frameworks, but I couldn’t find the last part which is shown in the image.38

Could you help me how I implement these kind of frameworks?
