Unable to play DRM/Protected content on Ungoogled-Chromium even after installing Widevine Plugin

I am using Ungoogled-Chromium Version 120.0.6099.129 (Official Build, ungoogled-chromium) (64-bit) on Windows 11 Home v22H2 b22621.2715. I downloaded the installer from here - https://ungoogled-software.github.io/ungoogled-chromium-binaries/releases/windows/64bit/120.0.6099.129-1

It doesn't allow me to play DRM content like Netflix/AppleTV/Prime etc.

For e.g. Apple TV website gives the following message when I try to play a show/movie.

I did stuff as per the FAQhttps://chromium.woolyss.com/#widevine

1. My settings for protected content chrome://settings/content/protectedContent

2. I downloaded the zip file from https://dl.google.com/widevine-cdm/4.10.2710.0-win-x64.zip& unzipped it

3. I enabled developer mod in the browser settings & loaded the unzipped directory

I see this on chrome://extensions/

In errors, I see the following

What do I need to do to play DRM content?
