WPAudioPlayer Can't get dowload link to show

I’m trying to get a download link to show up for my audio players but so far without success. One of the pages with such player is at:

https://www.lifeonpurpose.com/for-individuals

I’m also wondering once this is worked out does that mean all my audio players will have download links or is there a way to designate which ones I want to have them?

Under General settings, I have Replace [audio] syntax clicked. I’ve also tried clicking on the other settings with Replace still clicked but can’t get the download link to show.

Under Feed Option I have Alternate content for feeds: set to ‘download link.’

Can anyone help me please? Thanks.
