How to show Inventory step in workflow only if required inventory exists?

Summary:

In Oracle Field Service, I have configured a workflow and added Inventory as the first step (see screenshot).

What I want:

• The Inventory step should only be visible if the activity has any Required Inventory associated with it.
• If there is no required inventory, this step should not appear in the workflow for the technician.

I see that under “Show available when” conditions, it currently shows “Always available (no conditions)”.

👉 My question:

• Is there a way to configure a condition under “Show available when” so that the Inventory step is displayed only if required inventory exists?
• If yes, what field or condition should be used to achieve this?
