I am using PNP modern search V4 webparts in SharePoint online site. where i have linked search box and search results webpart. i need to highlight the Searched keyword in search results, i referred some documents where it stats "HitHighlightedSummary" will return the summery with highlighting the matched keywords, but in my case its simply returning the summery without highlighting the keywords. i am not sure what i am missing.
i have tried adding "HitHighlightedSummary" in Hit-Highlighted properties to but result is still same.
please find the below image for reference, where i have searched with word GCS but in "HitHighlightedSummary" it still returns plain summary.
