@ffmpeg/ffmpeg: Uncaught (in promise) ReferenceError: SharedArrayBuffer is not defined in ReactJs

Hi my problem is very similar to this one @ffmpeg/ffmpeg: Uncaught (in promise) ReferenceError: SharedArrayBuffer is not defined except that I do not have a nodeJS backend in my app. I would like to know if I can set the headers from my react app itself or I need to implement a backend script for this.
