How to approach women IRL who like me?

In terms of looks I am a 7 or 8 maximum. Whenever I go out, I find a lot of girls are checking me out. But they never approach me.

Yesterday's example : I was travelling in a bus. As soon as I entered the bus I saw this pretty girl. She was checking me out as well. Throughout my entire journey she was talking with her colleagues and constantly checking me out. I sensed that she wanted to talk. If I had approached her, she would have given her number or insta. But I didn't because of social anxiety. Neither did she.

This type of things happens multiple times with me in multiple different scenarios.

I understand that women rarely approach men in our country. I have to do that part. But how? Fellow redditors. Suggest me your strategies. How to politely start talking to them Without being a creep. What should I say to them?

Also would love to have perspectives of girls in this matter. Would you like to be approached by a guy whom you were checking out, or would you rather prefer to be left alone. What kind of talk would get a positive response from you?
