Ask her out for coffee.
I am not gay (have only recently identified myself as bi) and I had a similar experience at work. It was with a work colleague. I rated to then go to her place for drinks after work with a bunch of friends, then started sitting next to her, then felt an immense attraction, and eventually we started to sit close enough that our bodies touched and after a while we both just kind of knew. This was my first experience with another woman.

I met another lady in a social setting that we both go to. We started to hug goodbye, then a small kiss. Then the hugs got longer. We then started messaging and grew our relationship that way.

If you like/love her, don't let anything get in the way of trying. You have nothing to lose
