How to break the ice when starting a new chat based community?

So I started a niched chat group for one of my projects.. Currently over 100 peeps joined in, but everyone seems pretty quiet.

Can anyone suggest some tips and ideas on how to get a convo going?

I'm also not the most extroverted person out there to be honest. haha

Ask everyone what they're working on.

Ask: "what's the biggest challenge you are currently facing?". That'll give you a look at your members pain points.
