Well there's effectively no space on the lefthand side of the notch. You must assume that side is going to be completely consumed by actual menu items.
Side note: If you want to check what icons might be buried by the notch, you can Cmd + Drag any icon from the menu bar to rearrange them. If you drag an icon through the notch, the other items will pop into view, if any are hidden.
