adding audio sermon

I feel dumb that I can’t see it, but I cannot see how to add a sermon on the sermon page. I’ve changed the image and the custom heading, but I cannot figure out how to add the actual sermon (I have audio, not video). I tried adding an Element, but I do not see an audio player in the list. When I switch to “Classic Mode” I get an Add Media button, but I don’t know how to insert media on that page’s coding and the Add Media button does not seem to be available on either the backend or the frontend editors.
