Need help integrating Njoy Keen 600 with HASS running directly on RPI4

I am running latest HASS core 2024.7.4, Supervisor 2024.08.0, OS 12.4 on a Raspberry Pi4 and I am trying to connect it to a USB-HID manageable Njoy Keen 600 UPS (specified in the NUT compatibility list).
My UPS is shown in lsusb:
Bus 001 Device 005: ID 1a86:7523
I have installed the NUT add-on and configured it like such:

However, when I am starting the add-on, I get the following permissions error message:

Add-on: Network UPS Tools
Manage battery backup (UPS) devices

Add-on version: 0.13.1
You are running the latest version of this add-on.
System: Home Assistant OS 12.4 (aarch64 / raspberrypi4-64)
Home Assistant Core: 2024.7.4
Home Assistant Supervisor: 2024.08.0

Please, share the above information when looking for help
or support in, e.g., GitHub, forums or the Discord chat.
