A girl put her hand on my abdomen and kept it there. Is this a sign that she is interested?

we are coworkers. Outside the office we were talking and she placed her palm of her hand on my abdomen (where the belly button is) and kept it here. Kinda like how in pics the girl keeps her hand on the guy’s tummy as a sign of them being couples.

i got a bit intimidated and nervous and went quiet when she did that because we dont really know each other and have only been familiar for around 3 months. We barely talked besides professional stuff (she is the HR at work). Then someone came and she backed off.
