Not sure if this answers your Q but you’ve got the option to set up to 4 widgets in the footer above the field named “Footer Bottom”
Both are accessed via the Usual WordPress dashboard …
They’re named Footer Widgets & Footer Bottom.
re the copyright text, OceanWP has certain preset fields that will fill for you and you can copy what’s in the default wording in Footer Bottom & use it anywhere (in their FAQ/documentation they list 10 or so IIRC)
? [oceanwp_date] will give you “? 2019” and change each year.
In Widgets there’s an option to add social media icons and you can pick they’re location, which includes any of the 4 footer widget slots.
Once you’ve dropped that into the widget location and opened the box up you’ll find a ton of ways to adjust size, html link, colour etc.
HTH
