How to add a new app to an existing Django project in production (Droplet platform)?

I need to add a new app to an existing Django project that has been running for 6 months for production use. What is the best way I can migrate the app’s model to create a table in the managed database that is connected to this project?

This Django project was installed in a Ubuntu 20 Droplet following these tutorials: https://www.digitalocean.com/community/tutorials/how-to-set-up-django-with-postgres-nginx-and-gunicorn-on-ubuntu-20-04 and https://www.digitalocean.com/community/tutorials/how-to-set-up-a-scalable-django-app-with-digitalocean-managed-databases-and-spaces.

Thank you.
