Was my coworker making a move?

Our workplace went to a restaurant and I was sitting with my coworker who is a woman. She works as HR.

The tables were kinda small so we had to sit so that there were 2 persons at each table. We were in the corner and a bit isolated from the others.

anyway, back to the story, she was talking to me and then put her hand on the top of my hand. I got a bit nervous and moved my hand back. She saw that and put her hand back on my hand. I froze up and didn’t do anything. She wasn’t talking at this moment and just looked at me.

Why did she do that? Was she making a move? What concerned me is that she is the HR.
