I have built an outlook add-in which extracts the details of a mail like sender, subject, the body of the mail, etc and shares it to another messaging app. It is similar to "share to teams" outlook add-in. I want it to deploy it mainly to get a permanent redirect uri for the idp authentication within the addin to login to the messaging app, and then thinking about deploying it for the usage by our clients.

but still a little skeptical on which one would be the best.
