Hi @Deshmukh, Vijit ,
Thanks for reaching out.
The Enterprise application in Azure AD provides collection of third-party software as SaaS applications that have been pre-integrated with Azure AD. These applications are easy to deploy and configure Single Sign On.
As your application is not present in the gallery, you can create your own application by selecting "Register an application to integrate with Azure AD" if your application uses OpenId connect to connect with Azure AD.
or you can choose "Integrate any other application you don’t find in the gallery" for SAML based application.
Then you can navigate to the application to configure SSO. Select SAML or you can change SSO mode if it is suppoerting open id connect.
Refer https://learn.microsoft.com/en-us/azure/active-directory/manage-apps/add-application-portal-setup-sso to configure the claims based on your third-party application.
Hope this will help.
Thanks,
Shweta
