Would we have Free Will Inside a Simulation?

Over the past couple of weeks on the show I’ve gone down the rabbit hole of simulation theory. The more I look at it, the stranger it becomes. We start to see 2 separate theories emerge that open up new questions for both. The first is simulation theory. Described as living in a computer generated program that is running to simulate a situation or an event. The other is we are living in a computer generated world but not part of a simulation. Everything around us is at its foundation a mathematical equation written using some sort of computer code that governs every part of our existence. But if either of these scenarios are true would we have free will? How would free will work inside software?
