Host Streamlit app in personal computer with custom domain

Hello guys, recently I bought on IONOS a domain. My plan was to develop my own Streamlit app and deploy it in a laptop I have “abandoned” at home in which there’s installed Windows 10. The app is developed and I just need to show it to the world!

Searching in the Internet through tutorials I didn’t see how to do it from scratch step by step.

Does anyone can provide me any useful resouces or instructions to do this?

Thank you for all!
