How to maintain Context and Continuity across different add-ins when downloading DOCX/PPTX files in Outlook add-in

Question

Hello everyone, I am working with an app that works with Word, PowerPoint and Outlook. The add-in content is the same across these office platforms when a file or email is opened.

When I download a word document I want to store data inside that file so that I can use the context from my Outlook add-in inside the Word add-in. Context is different between add-ins, so that is why I want to store the data in the file as attributes that I will be used in the add-in to open the file in the same position/page/tab I left my activity from the Outlook add-in.

I will appreciate your help about how to achieve this behaviour in the project. Thanks.
