Is it possibe to remove/disable default context menu item "Add New... Ctrl+N" in the admin client for NodeItems.

We created NodeItems in our Plugin but the items will be populated by the plugin (there are hardware device that can’t be added by operator).

Is there a way to stop a user clicking on “Add New”, like disable or remove that default context menu item?

Please see this relevant method ItemManager.IsContextMenuValid -

There is a few samples using this method, for example – BatAction https://doc.developer.milestonesys.com/html/index.html?base=samples/pluginsamples/bataction/readme.html&tree=tree_1.html so please explore it and see how to use it.
