Where can I find the item path?
Most bricks require the Microsoft item path. You can find it by clicking on the filename in the top left on the page. In this example below, the workbook path is /MyFolder/Example.xlsx:
Why do bricks only support the item path?
The Microsoft Graph API allows you to identify an item via its id or path. However, we recommend using the path over the id because the former is accessible in both the UI and the API while the latter is only accessible via an API call. See Where can I find the item path? for directions on finding the item path.
