Authenticate different users in different browser tabs

Our app allows admin users to create basic child users. In some cases, the admin user will need to perform actions from the new basic users’ accounts, so we’d like to allow them to maintain their admin login session in one tab while logged in as different users in other tabs, just like Google allows you to sign in with multiple accounts in multiple tabs.

I haven’t been able to find documentation on how to accomplish this with Auth0 — can you point me in the right direction?
