How about turning the game I made on the cocos engine into a trial advertisement?

Hello everyone!
production time changed to -delivery time
I usually make small Facebook games, but today my boss asked me to make a playable ad.
I’m making a 2D game on the cocos game engine, but I don’t know how to build a trial advertisement that fits the Facebook channel.

If anyone knows about this please let me know, thanks!
