Using PCB A4998_M_MT_F_BT (temp probe, LED, Buzzer + OLED)
Once i power on the buzzer is continuously On, i am using a 3 pin type buzzer with VIN, Trigger connected to A3 and GND pins.
config file is attached.
Not all buzzers are the same. Obviously a 3 pin buzzer is different, the parts list recommended a pin buzzer, so if you buy different items then you can except a higher chance of things "not working" :-)

Problem solved, by changing 0 to 1 and 1 to 0, i guess for Active Buzzer its reverse logic.
