Can't get HDMI-CEC to work in Docker

Configuration
1

This is pretty much the same issue as Docker: Error during setup of component hdmi_cec, which was never addressed and is still an issue 5 years later from the looks of it

hdmi_cec:
  platform: media_player
  devices:
    TV: 0.0.0.0
    Fire TV Stick: 1.0.0.0
    Games Consoles: 2.0.0.0
    Media Server: 3.0.0.0
    VHS / DVD: 4.0.0.0
    Laserdisc: 5.0.0.0
  types:
    hdmi_cec.hdmi_1: media_player

And i get the folowing Error

Logger: homeassistant.setup
Source: components/hdmi_cec/__init__.py:206

Iā€™m sure this is not in the pristine HA docker image. Any explanations?

Ah yes, I forgot to mention I use the linuxserver.io image which increases security, it basically pulls down the official one and applies some environmental updates to the user and such so it doesnt run as root.
