Support staff does NOT have access to your project, so if it is necessary to investigate your project in the Modeler, you should provide access to Support. Here's how you do that:
Step 1: go to the project settings page and locate the security settings on the right.
Step 2: Select the grant support access item.
Step 3: Toggle the support access switch to the right (green) and select save.
Support employees can now access your Project in the Modeler, until you disable the Support Access. You are able to see this on the project info page ([i] tab) by the yellow Support access section at the top left of this page.
To disable the Support Access, go to the [i] tab and see the information about the Support Access being active (when and by who). Click the button [Stop support access]
when it is no longer needed.
