Page Composer Customization: Making Change Line DFF as Required

Summary: Making few change line DFFs as mandatory for ECR-PQM change type and draft workflow status.

Content (please ensure you mask any confidential information):

We have a requirement for making few change line DFFs as mandatory for ECR-PQM change type and draft workflow status. I have tried achieving the same through page composer by adding an expression for required field of the respective DFFs (as shown in screenshot), but the properties of change type and workflow status don't seem to be accessible on the affected objects page.

I've tried this expression -> #{bindings.TypeName.inputValue == 'ECR-PQM'} for checking the change type but it always returns false. This expression works as expected in general information tab but not in manage affected objects tab.
