Currently there is not way that an organization level admin can remediate an incident. The only way for an organization admin to do this, is if they become an account level admin. Being an account level admin would give the client organization admin access to all of our partner dashboard.
Essentially the organization admin role doesn't do anything but allow you to create users and that's about it besides they can view all of their info.
I hope that you can see how this is not ideal and decide to treat it with priority for your partners.
