How to make progress bar move with input mic sound?

I want the progress bar to go up and down depending on the microphone sound.
I made UAudioComponent and USoundWaveProcedural in c++. It can receive microphone sound. Now I want to visualize this.
I want to import a microphone sound into the WidgetBlueprint. Amplitude or frequency?
I searched and tried to get ‘Get Cooked Envelope Data’ and ‘Get Cooked FFTData’, and the result is False.
I don’t even know if I did it right. I honestly don’t know what this is.

Please help.
I also added an audio capture component.
But I’m not sure if this can only receive mic input.
If other microphone inputs are also received using the server, will all of those inputs be received?

Thank you in advance.
