Social links do not exist

Hi, I use Kids Camp. My site I have to make it in multi-language, and unfortunately, the plugin I used Polylang always creates problems. So I thought of using social links to the various languages on the site. So, for example, instead of using the facebook logo use the flag of spain. Is this a feasible idea? If YES, I can't activate the social links since, following the proposed procedure (Go to "Appearance => Customize => Theme Options => Social Links"), I don't see the relevant item. I thank you for the support Regards Translated with www.DeepL.com/Translator (free version)
