How can i use users from my partner's application to single sign on

问题

Is it possible to use Single Sign On based on users from ApplicationA to get in to ApplicationB? If yes how it should work in Azure AD portal and how should I use API to reach this goal?

Now I am able to authenticate users which have an account on Azure/Microsoft services, but I want to allow to get in to my application (ApplicationB) only users which are registered in my partner's application (ApplicationA).

I use OAuth2 protocol and python's libraries to handle all of this.
