Milesighr WS301 - NFC

Hello Everyone,
I just bought a door contact sensor Milesight WS301.
It is supposed to be configurable through NFC with Milesight Toolbox app.
I have downlaoded the App on my iPhone (13 Pro and 15 Pro) but the app could not detect my sensor.
Does anyone has been able to use their iPhone to configure any Milesight NFC enabled device?

Thks for your feecback,
