CL Expression to hide the Guided Journey task

Summary:

We have added a Guided Journey on Shopping Cart page to call a BIP report to show Item Relationships.

We are trying to show or hide the Guided Journey Task based on the CL expression i.e. show only for Inventory Requisition.

It is working for the Header variable but when I use the Line variable, it is not working.

Content (please ensure you mask any confidential information):

Below condition is working. It shows the Guided Journey task when Requisition number is equal to 895691 else it hides.

[[ $base.flow.variables.activeRequisitionDetails.RequisitionNumber == '895691' ? 'REPORT' : 'XXXX' ]]

But our requirement is to show the Guided Journey task only for Inventory type Requisitions, but when we use the line variable it is not working.
