How to decode Azure B2C cookie

问题

I have hard time making my Azure B2C renewing procedure work. So if my cookie is visible when I access the login url (login.microsoftonline.com), under x-ms-cpim-sso:myApp.onmicrosoft.com_0, is there a way to decode its value?

I would like to see when it expires and other related iformation.
