How Should I Approach Her 😅

So i am software engineer working remotely and situated at my hometown (Tier 2) , after signing off day I go to a public park daily except Sunday’s for run there i found a girl who comes to the same park with her dog for max 10 min and then leave i am highly confident she is giving the positive sign that she is interested but i am damn sure she will not initiate . I go there we have long eye contact none of us utter a word then she leaves . I feel sad daily that i have missed that chance to speak i need help how should i approach her mind you there are other people too have walk in the park

I really want to speak to her and i am that introverted man when it comes girl
