I'm calling the message-store endpoint and see the attachment URI, but when I attempt to view or download the file, it's binary data, and I can't play it or anything.
Am I missing something about how I should actually obtain the file or link to it for playback?
I'm attempting to send voicemail messages into Slack so that they can be played by teammates that miss calls.
I feel silly, since I don't see this being asked by anyone else and I'm not sure how/if anyone else is trying to do something similar.
