SparkFun RTK Facet -ESP32-WROOM-32D PCB Antenna Gain

Does anyone know the gain for the PCB antenna that is used in conjunction with the ESP32-WROOM-3232D WiFi/Bluetooth Module?

Is this the WROOM module with the built in PCB antenna? If so,it’s probably a unity gain antenna. You’d need to contact Espressif to find out for sure unless it’s noted in the datasheet.
