Trouble with Publishing Widgets

I am having trouble getting the glossary widget to appear it the .exe file I published.  I know you cannot use it in .html, but if there is no longer support for flash, then how can I use this?  Using Adobe Captivate 2019 and have dug through the Lynda videos, Adobe’s tutorials, and even the book by Pooja Jaisingh.  What am I missing?
