For the Analysis framework membership mutation we can use the bulk mutation.

mutation MyMutation(
              $id: ID!,
              $afMembership: [BulkAnalysisFrameworkMembershipInputType!]!,
              $afMembershipDelete: [ID!]!
          ) {
          analysisFramework(id: $id){
            analysisFrameworkMembershipBulk(items: $afMembership, deleteIds: $afMembershipDelete) {
              errors
              result : AnalysisFrameworkMembershipType
          }
        }
