Category Permissions/Security Settings

In Actions - Create Category, i want to grant full permissions to the group i’ve created in action 5 and remove ‘everyone’

I couldn’t find anything in the guides here and think i’m on the right track as the settings above remove ‘everyone’ from the settings, but they don’t add the newly created group. No error message and the category is created but with no-one having access.

It might be helpful to set the 1st action (assigning the group) to happen after an earlier step in the wizard than the 2nd action (assigning the security level).

I’m not sure, but I suspect that if the actions are run at the same time, that object might not pass through nicely.
