You can only have one bar on that, with two containers. Example, you can change your header bar flex layout to the column, then the two containers will stack together instead of side by side.
Then add your social icons and logo on the first container and your tab in the second container.
And yes, footer can't be set as sticky, especially the sticky setup requires a trigger (like when scrolled and so on), plus the footer is in the bottom where it requires scrolling up to the end.
Maybe what you're looking is something like ConvertPlus' info bar where it can be set as floating bar in the bottom.
Hope this helps.
