But how do you go about opening them up at work?
For once something I have experience in

(kinda)
Where I work there are a fair few HBs and personally I found a great way to open them is just ask them if they know about a certain product that a customer asked you about (if in retail which is what I do) then make a little joke about the customer or something situational like that, then later on open them again with the same situation with a different joke, ask her name and just get into a conversation.
Now what I've said above isn't concrete but I've done it a few times and it's worked. Another simple way of doing it is just by being humerous with other coworkers around her (like within her vision or hearing) then saying hi and asking her name and so on. I think the coworkers thing gives you social proof and it helps if you know allot of people in the workplace because it seems like you're "the guy to know" in a sense. The way I got one going was by isolating her whilst we were both on break (if that's possible for you I don't know) generally breaks where I work are pretty boring and people are always up for getting into a conversation especially if it's someone new that they'll be working with. You can never have too many friends in the workplace.
I'm pretty much rambling here but hopefully I've said something right in that mess of text above
