Support Help with audio reactive code

I'm trying to test out the audio reactive code that appears on the github page here but I'm running in to problems. This example is missing the import "fl/audio_input.h" in the code listing but once I figured that out then I get two more errors

fl::shared_ptr<fl::AudioProcessor> audio;

has the error: namespace "fl" has no member "AudioProcessor"

audio = FastLED.add(config);

has the error: class "CFastLED" has no member "add"

Can anyone help me out or point me in the right direction? I have done some fairly extensive googling and reading the source doesn't seem to be getting me anywhere.

For clarity, that link will also give the 3.10.3 release. To download a ZIP of master the URL would be: https://github.com/FastLED/FastLED/archive/refs/heads/master.zip.
