I'm building a solution that integrates Dynamics 365 and SharePoint Online. I have two packages: SharePoint add-in and Dynamics 365 app (managed solution). My plan is to submit the SharePoint add-in to the AppSource Store and describe that the SharePoint add-in works in conjunction with other add-in (Dynamics 365 app) that is available from the provider. The Dynamics app creates Application user and in this way I' able to achieve server-to-server (S2S) authentication. My question is - is this approach allowed by the AppSource policy? My understanding of 5.9 and this post is that the described scenario is not against the policies which means - it is allowed? If someone knows better channel to verify this - please let me know. I highly appreciate any help!
