The Java Quickstart launcher is designed to use only JWT or ACG, not Implicit Grant
The Implicit grant can only be used by SPA, which is not part of the launcher code. Authentication paths
If you are not sure how to implement the Implicit grant from SPA, please open a support case through the support center or follow the Implicit Authentication guide
