Chromium: how to make it use Widevine DRM without relying on Google Chrome?

On AlmaLinux 8.10, how to make Chromium "Version 133.0.6943.141 (Official version) Fedora Project 64 bits" use Widevine DRM without needing to install Google Chrome? The (alternative) Install Widevine alone without Google Chrome method detailed on the "proprietary/chromium-widevine" repository on GitHub is not being able to make the two software cooperate, as confirmed by Bitmovin's DRM Stream Test . I don't know if it could be a solution, but I tried to replace chromium by chromium-freeworld to see it the added codecs it promises would solve my problem, but the GetPageSpeed requires me to pay for a subscription to their repository. I see no advantage in paying to download chromium. TheTechLife 's tutorial is not for RHEL-based distros and cannot be followed. I did as Andrea Fortuna instructed, but the tutorial is more than 5 years old and does not work anymore.
