Any advice?
Please don't say it's all about confidence and all that bs because I don't believe it.
It is best if your first sentence arouses her curiosity. For example, I said to her, "I am in a good mood today, thank you!" A woman will definitely be very curious when she sees your sentence and will definitely ask You, "What does it have to do with me when you are in a good mood? Why do you want to thank her?" You naturally lead her to chat with you. This is a kind of guided chat thinking.
