purpose of some permissions

I couldn’t find much information about these permissions and am trying to understand their purpose. Could someone explain who typically uses these and for what scenarios?

datastudio.datasources.setIamPolicy
datastudio.datasources.settingsShare
datastudio.workspaces.createUnder
datastudio.workspaces.moveIn
datastudio.workspaces.moveOut
lookerstudio.pro.manage

Any insights would be greatly appreciated!
