I have an app WIP, using next-auth0 and want to have the users be able to log-in without refreshing the page. For example I have the functionality for users to upload large files and don't want to have the upload get interrupted by the user deciding the log-in part way through.

The only thing I tried so far is having the universal login form appear in an iframe and hoped to go from there, until I realised the form is actively blocked from working in an iframe.
