Unity Hub Does Not Show Window

I am having a minor issue with Unity Hub: After clicking on a project it loads Unity Editor which is fine. Now if I switch back to the Unity Hub app, there is no window. It is closed and there is no option in the menu to reopen it. The only way to get back the window is instead of switching to the app you need to re-launch it -- even if it was already running, magically the window comes back...

Same thing happens if I press ESC key on Unity Hub...

I am on MacOS Mojave, if that makes any difference.

 

Thank you. You mean the Dock? Yes that works, window comes back when I click on that, but hiding the window upon task switching (aka when I press ⌘+Tab) is still buggy (clicking with the mouse is lot slower than press a key combo on a keyboard, so I try to avoid that)
