----

> [!IMPORTANT]
> Add `prompt` and `include_granted_scopes` to Google OAuth params in
`GoogleProvider`.
> 
>   - **Behavior**:
> - Adds `prompt: "consent"` and `include_granted_scopes: "true"` to
`authorizationExtraParams` in `GoogleProvider` in `google.tsx`.
> - Ensures user consent is always prompted and previously granted
scopes are included in Google OAuth flow.
