Can I catch up the log while authentification through auth0?

Hi Team. I set up an auth0 tenant for my next project and 2 organizations on the tenant.
I want to have a division dialog for the organizations when I sign up or sign in.
But if I sign up with username & pwd on my project, happens an infinite loading on it.
How can I catch up the log or error on it? and where?
Please help me.

I could confirm the user info I tried was already registered on auth0 as a user in the user management tab of auth0…
Signup was success but why had the login page the infinite loading on it?

oh, I found the monitoring page. sorry for inconvenience.
