so this might be a stupid question but as I am a complete beginner I will need some help with this - I have no idea how to bring back the toolbar under the Editor type - I am not even sure of the correct name for it so I am attaching a screenshot. I am using Blender 3.0 on mac
If you should ever encounter this problem again, if I understand the question correctly you were looking for these "tools":
These are the Properties Tabs, they belong to the Properties Editor. In your screenshot it shows you have switched both editor windows in the right column to the Outliner. To get the Properties back, click on the dropdown menu in the top left corner of the editor window you want to change. There you choose Properties.
