NW7.3 Cannot Locate Deployed VC iViews in Portal Content Management

Dear Experts,

I worked on NW7.0 previously, and deployed VC applications will be placed under Portal Content Management > Portal Content > Visual Composer folder.

From there I can assign VC iViews into desired role.

But then, now with NW7.3, I cannot locate deployed VC applications under teh same folder. Please assist where can I find them and assign them to role.

Million Thanks,

Lai
