How to allow public read data from Kinvey, but authenticated access on create/edit/delete

Question

I set "shared privacy" for collections privacy (only owner may edit/delete - Bob).

If other user (Alice) authenticated, she may view Bob's records correctly. But if Eve (unregistered user) wants to read Bob's record, she gets an error:

{
  name: "NoActiveUser",
  description: "You need to be logged in to execute this request."
}

What should I do to allow Eve access Bob's record?

Thanks
