Check if user exists from login page

[graficosmorales]

In the login page I want to hide the “login” button if the user’s “mail” does not exist in the database and that this returns a message as “user not found”.
But when entering an email from a user that does exist, the “login button” appears

I had that condition on the button, but it stopped working
