Open Excel document that requires a password to modify

I’m using Excel Package Version 2.0.6479.13204 - I don’t see any updates available, so I believe it’s the latest version. I’m using Enterprise Edition Studio 2017.1.6435 and Excel 2010 (32-bit)

I’m not seeing password as a field in the properties window for the workbook read range activity? See attached screenshot:
