Hi Marino Valentino, thanks for answering my question.
If I understood you correctly, you want to create an Azure Workbook that requests data from the mentioned Microsoft Graph endpoint and displays it in the Workbook.
Unfortunately, this is not currently possible because Azure Workbook does not have an OAuth function to query the Access Token. A one-time creation of the Access Token would be possible with an AzureAD Enterprise App but makes no sense as I assume you need live data which is only possible with an OAuth lifecycle in the background.
If the reply was helpful, please don’t forget to upvote or accept it as an answer, thank you.
