 It is possible to pass an empty `config` string to indicate that no initialization of the underlying native Approov SDK is required. This initializes the service layer in a bypass mode, allowing you to obtain a standard, non-Approov protected Retrofit client. If you attempt to use any direct native Approov SDK functions (such as `fetchToken` or `precheck`) while bypassed, an `ApproovException` will be thrown. You may later call `initialize` again with a valid `config` string to enable Approov protection for Retrofit instances obtained after that point. Retrofit instances obtained while bypassed remain standard, non-Approov protected clients and should be discarded if protection is later enabled.
