Changing Social Share Icons for Olsen Theme Posts

I like the built in feature of having social share icons for each post, and am happy with the appearance of the icons (which match the theme style); however I so far I can’t figure out how to tailor them to my social media preferences. I would like them to be the same as the social icons readers can click to follow me, as in my main menu for example.

So for me, instead of the built in social share icons for each post being:

facebook, twitter, linkedin, pinterest

I would like them to be:

facebook, twitter, instragram, pinterest

How can I change this?

Thanks!
