+* Once you login via cli you need to follow theese steps (1-3) on your local: [Vertex AI Gemini API Beginner Guide](https://cloud.google.com/vertex-ai/generative-ai/docs/start/quickstarts/quickstart-multimodal?cloudshell=true#gemini-beginner-samples-drest)
+* Finally you can create JWT key by: `gcloud auth application-default print-access-token` on terminal
