Hello @geokongr,
You can use HTML for that. One example would be (to be placed in Appearance > Customize > Footer Bottom):
<div class="oceanwp-row clr">
<div class="span_1_of_3 col col-1">
<ul class="my-footer-social">
<li><a href="https://url" target="_blank"><i class="fab fa-facebook"></i></a></li>
<li><a href="https://url" target="_blank"><i class="fab fa-twitter"></i></a></li>
</ul>
</div>
<div class="span_1_of_3 col col-2">Copyright 2020 - My Website Name</div>
<div class="span_1_of_3 col col-3">
<ul class="my-footer-menu">
<li><a href="https://url" target="_self">My First Menu Item</a></li>
<li><a href="https://url" target="_self">My Second Menu Item</a></li>
</ul>
</div>
</div>
But you will also need to create accompanying CSS styles for these classes in Custom CSS section in the Customizer in order to achieve the desired look (font-size, color, padding, etc).
Hope this helps. Best of luck with your website
