If you want to remove a workspace template permanently, you can delete it.
⚠CAUTION: You can't undo this action. The only way to recreate a deleted workspace template is to create a new one.
Click the Reporting tab.
In the left-hand menu, click Workspace Templates. You can see your 'Published' and 'Draft' templates.
Click the option where the report sits currently, for example, Published.
Click the report, then click Delete.
📌TIP: If you only want to remove a workspace template so that other users can't see it, but you don't want to permanently remove it, you can use the Unpublish option instead.
