How do I save requested audio using the varset plugin?

In Unreal Engine, I am using the varset plugin. I want to use the “get” method to request the audio, but I don’t know how to get the audio and save it.

I want to convert the python code into a UE5 blueprint, here is the code that uses the “get” method to request to get the audio saved locally.

if response.status_code == 200:
    save_path='C:/Users/Administrator/Desktop/test.wav'
    with open(save_path, 'wb') as file:
        file.write(response.content)
    print('File downloaded successfully.')
