How to schedule an RFC in My Oracle Support

Hi,

I am new to Oracle support and I had raised an RFC on behalf of a client. Oracle support have responded asking to provide authorized approval and schedule using
self-scheduling service via MOS.

MOS > On Demand tab > Change Management > select the RFC you want to schedule >  from
ACTION drop down list select "SCHEDULE & APPROVE" > select the date and time by
pressing "“GET TIME”  and submit

But I can't find the Change Management on the On Demand Tab (Now called Manage Cloud)

Could someone please guide me in the right direction?

Thanks,

Shantanu
