Theme options: missing "Social Links" and "Social Icons"

Hello, today i bought the Fotografie Pro Theme. I wanted to add the social media icons (incl links) to one of my menues, but I cant find them. In the faq is written: How to add Social Link? Go to “Appearance => Customize => Theme Options => Social Links” Add links for social media under the mentioned box You can find further option to change social icon size under “Social Icon Size(px)” But in my Theme Options are nothing about the social inkls or icons. And yes, i do have the Pro version :-) I´m using WordPress 5.2.2 Does anyone have an idea where to find now or is it a bug in my version? Many thanks Oliver
