@ntruchsess : I would need your help here regarding the comment for moving the method after CreateCentralIdentityProviderOrganisationMapperAsync ,ref : #1010 (comment)
So i moved the method in this file IdpManagement.cs, now in order to use this file in Registration service i have to inject dependency using the method AddIdpManagement from src/externalsystems/Provisioning.Library/DependencyInjection/ProvisioningLibraryExtensions.cs but then it requires configuration to be added in Registration service which doesn't make sense as they are not needed in registration service.
