How To Save / Download Messenger Audio Recording?

My good friend sends me candy audio on FB Messenger. She offers me permission to avoid wasting and use them in a musical piece. However, I can not appear to determine how. In Safari I attempted going to Develop -> Show Web Inspector. Then within the Sources folder I discovered a folder Other that appears to have mp3s, however all of them simply make one fast clicking sound and are not her message, which is about 8 seconds lengthy. Do you understand how to avoid wasting this audio? Much recognize in the event you share it. Thank you!
