I've created a SharePoint Embedded application (as described in the training session https://learn.microsoft.com/en-us/training/modules/sharepoint-embedded-create-app/). After having created it, I wanted to subscribe to the notification system to get a function triggered, when a file changes (https://learn.microsoft.com/en-us/graph/change-notifications-overview#supported-resources).
Following the guides in https://learn.microsoft.com/en-us/graph/change-notifications-delivery-webhooks?tabs=http, I finally came up with an Azure Function, which I could register for the root of my SharePoint Embedded container.
But I found two things, which I couldn't explain and therefore would like to ask here:
1. I couldn't get a notification triggered by uploading a file via Postman - a setup I had from another training session (https://learn.microsoft.com/en-us/training/modules/sharepoint-embedded-setup/)
2. I couldn't get a notification triggered editing a file using the Excel application on my machine, but I could get one triggered using Excel online.
3. When I received a notification, I couldn't trace back which item got changed, because I only got a reference to the root of the container (similar to https://techcommunity.microsoft.com/t5/sharepoint-developer/sharepoint-webhooks-notification/m-p/402...).
I highly appreciate any form of help or clarification, which might help me to debug this further!
