So what exactly do you get from the Madrazo Files after completing the Perico Heist? GTA 5 Online

So... me and some buddies of mine finished the Cayo Perico Heist and we got to see the final cutscene of the heist. Yeah, let's just say we weren't expecting it... Definitely did not think that's what the files were. That's Madrazos reward for us completing the heist. Enjoy. I guess.
