Importing Captivate Draft created audio on a stand-alone system

I am creating a project in Captivate 2019 (64bit). This is being built on a stand-alone system i.e. it is not connected to the internet for security reasons. For these same reasons, I cannot record audio as I cannot attach a microphone. 

I can capture audio-only narrative in my Captivate Draft which is connected to my personal Adobe account through the internet. I do not have a personal subscription to Captivate.  

With the project I am building on the stand-alone work computer, I cannot drop the audio from this personal account directly into the project. Is there another way of retrieving the audio captured on Captivate Draft slides saved to the Adobe account so it can be saved to CD / DVD for transfer to the project?
