Should I take things casually or just simply trigger the gun?

So, today I went for a meeting with a lady. I'm in a foreign country where I don't speak the language and I own her through a language learning app. Then we went on a walk around the park. After that she invited me to her friend's place where there are 2 of her lady friends there. And then we drank some wine with sole food and chatted a lot and had fun. After that end of the day I told her "I just reached home. Let me know when you'll reach. I had a great day today. Let's hangout soon" and then she replied me "I’m at home ). The spontaneous solution are the best😄 I had a fun time!" so how should I do things? Should I just ask on Sunday morning, "would you like to go on a dinner date?" Or how should I move forward from now? Or just meet with her more? Or just simply ask if she's interested in dating me?
