I am having trouble rendering the description/content managed property called RefinableString02 in the pnp-modern-search's Search-Parts web part.
My solution was to add a custom web component below and adding it to the handlebar edit code section in the UI, but the description/contents still not showing.
<document-card-content-component
data-description="{
{RefinableString02}}"
data-content-string-param="Test value"
data-content-object-param="{
{JSONstringify this 2}}"
</document-card-content-component>

Other solutions are appreciated.
