Waiting for Approval - RFx Question

Hi Experts,

We are in Esourcing 7.0. My Client has a requirement to add spend category group as approver for RFx before it go to next phase 'Open for Review'.

I modified the document security template for RFx and provided the group information.

Added them as Colloboraters - Role (Approver)

When I changed the phase to 'Waiting for approval'. I dont see any approval item in the workbench (My Workflow Activities)...

But when I click on the link(that I received in email as colloborator) , I can view a button 'Approve RFx'.

Is there something I am missing?

Will 'My Workflow Activities' only shows that are routed through XPDL  (Project and Contract Document)?

Thanks,
