I want to know about the coexistence use of WIFI/BLE on the ESP32

　　I want to know about the coexistence use of WIFI/BLE on the ESP32.
I heard that there is CONFIG_ESP_COEX_SW_COEXIST_ENABLE Enable option in menuconfig.
Is that available if I select it in menuconfig ?
　　However, I am using the ESP-S3 development board to create an application that accesses both Wifi and BLE in the Arduino IDE development environment.
In the configuration on the Arduino IDE, I cannot find any configurations about CONFIG_ESP_COEX_SW_COEXIST_ENABLE.
　 I am not sure if I can enable the CONFIG_ESP_COEX_SW_COEXIST_ENABLE option on the Arduino IDE. Does anyone know how to check if the ESP32 CONFIG_ESP_COEX_SW_COEXIST_ENABLE option is enabled on the Arduino IDE? Could anyone please tell me how to do that?
Additionally, When I checked the project file, it was located in user directory below: AppData\Local\Arduino15\packages\esp32\hardware\esp32\2.0.11\tools\sdk\esp32s3
I found that “CONFIG_ESP32_WIFI_SW_COEXIST_ENABLE=y” and “CONFIG_SW_COEXIST_ENABLE=y” are in sdkconfig file. And I also found that “#define CONFIG_ESP32_WIFI_SW_COEXIST_ENABLE 1”
and “#define CONFIG_SW_COEXIST_ENABLE CONFIG_ESP_32_WIFI_SW_COEXIST_ENABLE” are in sdkconfig.h file. Does it mean that these options are enabled in the current SDK?

Note that coexistence is always enabled. That switch switches between software and hardware coexistence. Software coexistence is a bit more advanced but uses more resources.

Thank you for your reply. Can I ask you more about this stuff? I want to ask you four questions.
The first question is that I want you to tell me which document I should refer to.
The second question, can you tell which coexistence mode it's running from the information I presented?
Is it software one or is it hardware one?
The third question, could you please tell me details on the functionality of the option (CONFIG_ESP_COEX_SW_COEXIST_ENABLE)? I expect the following differences.
If disabled, Wi-Fi processing and BLE communication processing must be performed separately.
When enabled, BLE communication can be performed by interrupt processing during Wi-Fi processing.
The fourth question is how to enable software coexistence? I'm developing with the Arduino IDE and I'm not sure how to enable the settings. Could you help me please?

Thank you for your message. Now I understand that the software coexistence option (CONFIG_ESP_COEX_SW_COEXIST_ENABLE) is selected by default in the Arduino IDE.
But there was no option matching CONFIG_ESP_COEX_SW_COEXIST_ENABLE within the Arduino IDE, I didn't know that option was selected. Could you help me where I can tell which option is selected, please?
　 In my research, I did found "CONFIG_ESP32_WIFI_SW_COEXIST_ENABLE=y" and "CONFIG_SW_COEXIST_ENABLE=y" in the sdkconfig file in my user directory in AppData\Local\Arduino15\packages\esp32\hardware\esp32\2.0.11\tools\sdk\esp32s3. However, I couldn't find the option "CONFIG_ESP_COEX_SW_COEXIST_ENABLE" that I'm talking about.
Now I have no hint so I want you to tell me which document I should refer to.
