Social media share description function not appearing in Branding section

[bkarr]

The Customizing Webinar Brand Settings says there is a Social Media Share Description section.  This is not appearing for me.  Did it go away or does anyone know if it is somewhere else in settings?

Social branding is when an individual, company or organization creates a unique brand persona that is shared with the public. This helps to build a stronger connection with consumers using social media platforms.
