How to setup the AppWrite database for this open-source demo?

I need to get this todo list manager to work, but there is no documentation on how to setup the AppWrite database (collections, document attributes) for it.
GitHub link: https://github.com/thepkpawankumar/todo-manager/tree/main

All I found is this screenshot, but it seems to be from an older version of AppWrite.
What does the key symbol mean and what values do I need to setup to make it work?

Thank you

you'll have to try and recreate it...looks like there's a string attribute and a boolean attribute

I tried, and I'm stuck at what kind of attribute $id is

It's a system attribute. You don't create it. have you read through our docs? https://appwrite.io/docs/products/databases

Looking at the code, this project would have to be updated for a current version of Appwrite. The most obvious thing I notice is that the version of Appwrite this project was built for did not have multiple databases per project.
