How to ask your ex-girlfriend to a date

It might sound stupid but I want to know how do people ask their ex-girlfriend out on a date. My ex and I started having coffee together about two months after our break up. For people who are going to ask, we broke up because we felt like our relationship was on a plateau, we weren't growing and that was affecting our feelings for each other in general. Our little "hangouts made me feel something for her again. The kind of feeling I had when I was still chasing after her.

They say the same technique don't work the second time. So I'm kind of lost right now of idea on how to ask her out on a date and I mean a romantic one. I was thinking if she'd agree, then maybe we can work things out. If she would say yes, it would really feel like getting my name called out for a win free tour. Help me please
