Shelly Wi-Fi Integration app - Password issue

For those 2 relays, shellyplus2pm & shelly2pmg4 the app is using this driver: V2+ Switches, Relays, Dimmers, Lights, Power Meters in the Integration app.
I have a password issue with this driver

The 2 relays are password protected, no username (empty)

When I try to install those relays, I get this message in the app:

When I remove the device, remove the password protection in the Shelly and reinstall it without password, everything is working fine. So, this is a kind of workaround to get the device installed and make it password protected afterwards

But when I look in the parent or child device I can't find a password field, I should expect it in the Parent/preferences tab?

Am I missing something?

@bobbyD , this app is still in Beta, is this the reason why the password field is not implemented (yet)?
