How to set the "og:image" for social sharing?

We have an image on our form that we'd like used as the image when shared on social networks. I've looked through the settings but can't see a way to make those updates. Please could you help? Thank you!

I have been performing some tests and was unable to set it using neither the logo feature or adding an image element to the form, I'm reporting this to our back-end team for further inspection.

You may also give it a try on your end and see if it works for you, here is how to set the logo or add an image:
