I have a Xamarin ios application from which I need to open/edit a word doc in MSWord app and later get the edited file in my application.
I followed the steps in the below link and unfortunately that didn't work.
https://docs.microsoft.com/en-us/office/client-developer/integration/integrate-with-office-from-ios-applications
That tutorial only works for files hosted in SharePoint or OneDrive.
Unfortunately other cloud services or local files are not supported.
From the link:
You can enable users who are running Office on an iOS device to open
and edit files stored in SharePoint or OneDrive from any application,
and then quickly return them to the original application when they're
done editing the file.
