Does adding each other on Instagram mean something for girls these days?

Got talking to this girl at a social meet up & towards the end we ended up adding each other on Instagram. I was gonna message & ask her out for a coffee but it occurred to me that it might seem too desperate because we only met in person once.

Or am I overthinking here?

Actually I will add that she asked me for my Insta & handed me her phone to put my id in. She did add other folks at the meet up too.
