Embedded Looker Dashboard: Disable "Move to Trash..."

[JoeR]

We’re using embedded looker dashboards / explores / looks. By enabling the save_content permission a user is able to edit the dashboard. They are also able to delete it. The Move to Trash... menu item is enabled. Is there a way to disable it?

I was hoping to manage all the Dashoard lifecycle OUTSIDE of the embedded frame.

If this cannot be done, are there any events I could identify a delete? e.g. sent from IFRAME back to parent?

Thanks in advance.
