I have two applications: let's say application A and application B that are running on different ports i.e. 6420 and 8000.
Theses applications are registered in the B2C tenant and are using the same 'signInUp policy'.
I am able to authenticate the user with MSAL.js (Microsoft Authentication Library).
Kindly let us know what needs to be done at code end for SSO implementation on different domain applications.
