Where to upload an mp3 file to get a link that can be placed in the description under the video on gumroad?

Question

Yandex.Disk

The problem is that gumroad does not perceive the Yandex Disk link to the mp3 file as a link. At the output, I want to get just a button by clicking which a person can listen to an mp3 file with a course description instead of reading it. Ideally, this is just a minimalistic button without ads and other nonsense like Yandex Disk . GOOGLE DRIVE is also not suitable because it requires authorization. It would be desirable that the mp3 file could be listened to by any visitor, even nowhere authorized.
