Thank you for your post!
When it comes to the List licenseDetails Graph API, you should be able to use the
?$select=servicePlans OData query parameter to help filter out your service plans and license details so you can see your Dynamics 365 Plan. You can also list by ID
?$select=id, to see the Product IDs for your licenses (i.e. Enterprise Mobility + Security E5).
If you're still unable to see your Dynamics 365 Plan, can you share a screenshot of what you're seeing?
If you have any other questions, please let me know.
Thank you for your time and patience throughout this issue.
