Clarification SRM permissions

Hi

I am having a go at installing SRM. I have added the required SRM roles to the permissions tab under the site recovery plugin for both protected and recovery sign.
There is also an administrator role specified as well since it is required.
Do I also need to assign my SRM roles to the vCenter objects? From what I understand the SRM actually uses the account used to make site connection so that to me says I would not need to specify them again.
