@john.gateley while I appreciate the response, those solutions are not what we are expecting in these situations!! 
ā¦ Iām in a similar situation. Have APP A and APP B where user can log in through NEW universal login. They click on a link to APP C which is a NextJS application using the Auth0 NextJs sdk. It would be great if I could use the standard configuration for my APP C as stated in the docs and receive something like a query parameter, through an API route on the server side to modify which database connection the authorize endpoint would attempt to check the session for. I have tried in the dynamic next auth route to extend the authenticationParameters to include āconnectionā : āname-of-dbā. This doesnāt seem to workā¦ any advice??
