On the simplified page under All Workspaces shows all the Workspaces that you have created and above it is create workspace lets you create a workspace. Then if you click on the workgroup you'll see all the people in that workgroup and drop down of workgroup will be all groups under it.
You will be able to edit workgroup by clicking on three dots in top right corner where you can rename workgroup or delete it and there's plus next to it that let's you create Group and Users as you need. If you have a user in workspace you can edit them by clicking on there own personal the 3 dot and you can remove there role on that workspace or delete the user from the workspace. On the workspace there is one last thing you can do next to the workspace name there is a bar with unlimited, 10GB, 5GB or 1GB which when changing that (Leaving this open ended for someone to type in the answer because I don't know what they do.)
Next if you click on a group you can only do two things a + that's let's you add users and trash can icon on user bar to delete them.
