Authentication for new users

I tried to set up an account for my new app CountWhatMatters. The six digit email verification code didn’t come through in time. I tried again to log in the next day and it said: ‘Please verify your email before logging in. Check your email for the verification code.’ However there is nowhere to enter the code (which I now have received), nor is there a button to ask to resend it and redisplay the code entry screen. I tried to fix this within Base44 with prompts, but it said it would need Base44 to fix it.
