Giving another committee member access to Application Manager

How do I give an adult volunteer access to the application manager in The individual has a my.scouting account and is a registered adult, I just cant figure out how to get them access. Thank you for any assistance.

I key 3 goes to organization manager > Functional roles > make a Key 3 Delegate - I think there is a Registration contact position or something - not sure they can approve applications - if you want them to approve Adult apps the COR has to sign on to same spot and give COR Delegate
