Gravity: Digital 10A Relay Module

Excuse me for probably dumb question, but is there a specific orientation in which the 10A Relay Module must be positioned, or did I simply receive a defective unit?
I've connected it to ESP32 board ("-" to GND, “+” to 3.3V and “D” to GPIO 15) and it appears that it only turns ON (NO) when installed flat on its back or upside down. Can't get it to work in a vertical orientation.
It just makes a very soft “click” but does not engage. It latches fully after I flip it over or give it a gentle smack with my hand.
Kindly, Arthur.
If you have a 5V supply (e.g., USB charger), try powering the relay module directly and see if the relay clicks reliably in all orientations.
ahsrab.rifat Yup, it indeed works just fine with 5V, but it's not really something I've been looking for for my project unfortunately.
Thanks for your reply though.
Kindly, Artur.
