# Gemini OAuth (OPTIONAL, required only for Gemini OAuth accounts)
# -----------------------------------------------------------------------------
# Sub2API supports TWO Gemini OAuth modes:
#
# 1. Code Assist OAuth (需要 GCP project_id)
#    - Uses: cloudcode-pa.googleapis.com (Code Assist API)
#    - Auto scopes: cloud-platform + userinfo.email + userinfo.profile
#    - OAuth Client: Can use built-in Gemini CLI client (留空即可)
#    - Requires: Google Cloud Platform project with Code Assist enabled
#
# 2. AI Studio OAuth (不需要 project_id)
#    - Uses: generativelanguage.googleapis.com (AI Studio API)
#    - Default scopes: generative-language
#    - OAuth Client: Requires your own OAuth 2.0 Client (内置 Gemini CLI client 不能申请 generative-language scope)
#    - Requires: Create OAuth 2.0 Client in GCP Console + OAuth consent screen
#    - Setup Guide: https://ai.google.dev/gemini-api/docs/oauth
#    - ⚠️ IMPORTANT: OAuth Client 必须发布为正式版本 (Production)
#      Testing 模式限制: 只能添加 100 个测试用户, refresh token 7 天后过期
#      发布步骤: GCP Console → OAuth consent screen → PUBLISH APP
#
# Configuration:
# Leave empty to use the built-in Gemini CLI OAuth client (Code Assist OAuth only).
# To enable AI Studio OAuth, set your own OAuth client ID/secret here.
