For station mode :
A configuration option :ref:`CONFIG_ESP_WIFI_ENABLE_WPA3_OWE_STA` and configuration parameter :cpp:type:`owe_enabled` in :cpp:type:`wifi_sta_config_t` is provided to enable OWE support for the station. To use OWE transition mode, along with the configuration provided above, `authmode` from :cpp:type:`wifi_scan_threshold_t` should be set to ``WIFI_AUTH_OPEN``.
