Need HELP - Connecting to a bluetooth slave that is password protected

Hi guys !

I am working on a project for which I need my arduino and its BLE module (I have most HC on stock) to connect to a password protected bluetooth device (It’s a camera).

The camera requires a passcode to be typed in order to connect to it.
While I’m ok with unprotected ble connexion, I have no clue about how to achieve this…

Any help / example code will be welcome !

Thanks in advance for your help !
