 - The SDK is configured with a `local_flags_config` object that specifies parameters:
     1) `api_host` - If your project is in the EU/IN region, this should be set to route to `api-eu.mixpanel.com`/`api-in.mixpanel.com` respectively.
     2) `enable_polling` - This should be set to `true` to enable polling for new flag configurations.
