    //Set style properties
    customStyle.CharacterFormat.FontName = "Calibri";
    customStyle.CharacterFormat.FontSize = 22;
    customStyle.CharacterFormat.Bold = true;
    customStyle.CharacterFormat.UnderlineStyle = Syncfusion.Drawing.UnderlineStyle.Single;
    
    // Find the first occurrence of the target text
    TextSelection selection = document.Find("Adventure Works Cycles", true,true);

    if (selection != null)
    {
        // Convert selection into a single text range and apply the style.
        WTextRange textRange = selection.GetAsOneRange();
        textRange.ApplyStyle("MyCustomStyle");
    }

    //Creates file stream.
    using (FileStream outputFileStream = new FileStream(Path.GetFullPath(@"Output/Result.docx"), FileMode.Create, FileAccess.ReadWrite))
