How do I apply glosstext style to glossary text in 2019?

Explorer ,

I am using RoboHelp 2019 and am trying to apply the glosstext style to the expanded text definition (red box on left in image below) on a glossary term. I have the glossterm style (yellow shading image below) applied to the term, but am unable to apply the glosstext style to the drop down definition text and keep it separate from the topic text. See attached image.
