Hello and Welcome @yeahSureHello
There are many layouts in Zorin Appearance and you did not say which one you use...Moreover you did not mention if you are using Zorin Pro or Zorin Core or Zorin (pro) lite. Please update this information in your profile settings.
Now if I am understanding it correctly, you are using the fourth layout that comes with both lite, core and pro. And you mentioned extensions, so you are using GNOME. If you want the dash to be visible always you can use 'dash-to-dock' extension and if you mean the top panel by 'activities dash' and want to add favorites in the top panel, you can use the extension called Flippery panel favorites:
the result will be like this:
