[Karthik-K-N]

Only need to update the methods in managedfields_test.go file like

cluster-api/internal/util/ssa/managedfields_test.go

Line 363 in fe23f8f

g.Expect(env.Client.Create(ctx, createCM, client.FieldOwner(tt.createManager))).To(Succeed())

.

Is it recommended to convert structured to unstructured before using Apply?
