Arch Linux: Webcam Virtual Background Setup

I have tried various tools like fakecam and blog posts like this (https://elder.dev/posts/open-source-virtual-background/) , however, I just can't get anything to run on my setup (Arch Linux). Can someone help me out and write me a how-to for dummies on how to get a virtual background or blurred background for conferencing tools like Skype, Zoom, Teams on Arch Linux?
