I am working on a project to create a multi-tenant app to allow Single Sign-On with Azure Active Directory to be used by customers in other tenants.
I am confused and wanted advice on below queries:
1. If I will provide the app URL to them will they be able to authenticate themselves using Azure AD of their tenant and can approve on the consent screen to get access to my app?
2. Do I need to add my app to the list of the gallery of enterprise applications on Azure AD?
3. Is it necessary to get your multi-tenant app added to the list of the gallery of applications on Azure AD? What are the other ways I can achieve it and give access to my customers on other tenants?
Thanks in advance!
