Girl I barely know at work found my number on system and catfished me?

What should i do about this?

I feel in a awkward position because this girl at work is like 5 years younger than me and she decided to find my number on work system and text me on whatsapp. She used a fake but realistic profile and after a while admitted who she was by eventually showing me her own selfies to me.

How should i go about this without it being awkward at work?

by the way in the text after i pressured her to tell me she admitted how she got my number but faked a elaborate story about why she did all this.
