Inserting applause in a document

Menu/Insert/Audio or Video.?

I can use Gallery/Themes and one option is Sound. However, it will only preview and I can’t seem to add it to my document.

If you use Gallery/Themes then a double-click on a sound opens Media player for preview. It has “Apply” button that inserts sound into the document.
