Inovelli Blue 2-1 Dimmer LED Bar - How do I control it?

I just installed an Inovelli Blue 2-1 dimmer light switch. I thought I found the PERFECT switch that met my criteria, but my S/O is sensitive to the littlest light while sleeping, even the VERY dim red light when the switch is off.
(We had to tape over other smart plug lights in the bedroom)

I’ve been able to figure out almost every “problem” I’ve faced in Home Assistant, (definitely NOT a power user) but it’s humbling to come to the community and ask for help.

I see the parameters on their website for controlling the LED bar, but I don’t know how to interact with those parameters, per-se.

In the GUI I can issue a cluster command, but I don’t know which cluster command to send… Others have been able to use YAML to do it, but again, I don’t know where I would issue the command.

HELP! Thanks!

I wrote a script (also available as a blueprint) that can control the effects and LED colors. I turn my fan LEDs off at night so you can only see the light switches, for example.
