I want to use query string parameters on SourceLocation on a Office add in(Word add in). I can add the query string parameters inside the manifest.xml file. How can I read them inside taskpane.html file

The query string parameters I used are stripped and not usable from taskpane.html file.

When I use Window location.search it does not have the query string parameters I added.

Is there any configuration on manifest.xml file or Office to enable query string parameters on SourceLocation
