Hey there, there is a section on the page that goes into detail about this particular action. To provide further information, you must use the buy command or the give command to obtain a physical shop creation item. Once the item is obtained, simply place it in a safe environment and ensure there are no conflicts with protection plugins.
P.S. In case you encounter any issues you have all direct links to my projects and support methods here at
