I’m making surveillance camera with pir sensor and esp 32 cam, i followed the code below but the notification is not working and i don’t know the reason. help me plz

// Ensure ESP32 Wrover Module or other board with PSRAM is selected
// Partial images will be transmitted if image exceeds buffer size
