ffmpeg.wasm plugin: React throws ReferenceError: FFmpeg is not defined

Description

Briefly describe the issue.

created new react app using create-react-app

Using screen share recording and saveAs works fine but when using plugin to convert it throws this error.

convert plugin using:

const videoJsOptions = {
  controls: true,
  bigPlayButton: false,
  width: 320,
  height: 240,
  fluid: false,
  plugins: {
    record: {
      audio: true,
      screen: true,
      displayMilliseconds: false,
      debug: true,
      convertEngine: "ffmpeg.wasm",
      convertWorkerURL: "../../node_modules/@ffmpeg/core/dist/ffmpeg-core.js",
      // convert recorded data to MP4 (and copy over audio data without encoding)
      convertOptions: [
        "-c:v",
        "libx264",
        "-preset",
        "slow",
        "-crf",
        "22",
        "-c:a",
        "copy",
        "-f",
        "mp4",
      ],
      // specify output mime-type
      pluginLibraryOptions: {
        outputType: "video/mp4",
      },
    },
  },
};

I uninstalled ffmpeg version 0.10.* then installed “@ffmpeg/core”: “^0.8.5”, “@ffmpeg/ffmpeg”: “^0.9.8”,

it works now fine with react. No idea why this worked
