A target with the same ID already exists.

      ID.unique(), // targetId
      token, // identifier
      this._pushNotificationsProvider
)```
after user login, I don't check previous target exists neither delete target when user logs out
but I'm using  `ID.unique()` so why does it launch this error?

Developers are experiencing an error stating "A target with the same ID already exists" when trying to update the user's phone from the dashboard. The issue might be related to not checking if a previous target exists or deleting the target when the user logs out. Despite using `ID.unique()`, the error persists. Solution: Implement a check to verify if the target already exists before creating a new one, and consider deleting the target when the user logs out to prevent conflicts.
