How can I create superuser in EC2 after contact using SSH(There is no app folder in EC2 instance)

I connect to my EC2 instance and I use Django and deploy with elasticbeanstalk. I'd like to check how many Users in my service...but There is no app folder in EC2 instance and don't know how to make superuser like using console

python manage.py createsuperuser

Is there any solution to check my users?(except make admin page or container_commands <- I already tried but it doesn't work. so I'd like to try the other way.)
