I recently noticed that in the Microsoft Teams Admin Center in the Manage App section, some apps are "customizable".
I am creating an app which will send requests to a software that is installed on-premises and thus has different domain name depending on the organisation using it (xxx.com, abc.com…).
Could I use this feature to make the domain name customizable by the Teams admin so that the app is ready to use by the Teams users.
I also wonder if and how I can use this customized data (I suppose it is manifest data) in my app code (note: I am using NodeJS).
Side question, I also noticed a "Settings" tab which is always empty, what is it for, how can I add settings to my app?
