Not able to parse string(Labels) from HTML & JS Files in Splunk Application using Poedit

Hello, We are using Poedit to extract labels from our Splunk application, but we are unable to fetch them from HTML & JS files. We are able to extract labels from .conf & .xml files. Please let us know what changes we need to do in order to parse string from JS & HTML Files. Note: Do we need to make any changes in : Poedit File PreferencesExtractors TabJavascript And there is no option for HTML Pages in extractor.
