Hi and welcome to Thunkable,
I don’t really get what you want to do. As the name tells “Facebook ads” are ads within facebook. You cannot implement them anywhere else 
Best, Chris
At the moment we offer access to the AdMob network as a monetization option for our PRO users.
We don’t currently offer integrations for any other advertising networks (i.e. Leadbolt or Facebook Audience Network) however if you want to explain a little more about your app and why you would prefer Facebook over AdMob then we can consider it further.
Thanks.
