How to find Unavailable and Committed fields in Inventory API?

Hi, I’m integrating Inventory API to manage product inventory. I’ve read the Shopify documentation but can’t find the Unavailable and Committed fields from the Inventory API. Please help me with how could I get those fields. I’m just new to the Shopify API. It would be more intuitive if you could attach images. Thank you very much.
