Hi
Want to post/view calendar without user signing in by using the client_credentail workflow. however result in resource not found error. Tried to search but no solution found.
My setup 

Using post to get the access token and check with jwt:
Tried in graph explore and delegated permiison path and it works: endpoint with https://graph.microsoft.com/v1.0/me/events
However when try with postman workflow:
https://graph.microsoft.com/v1.0/users/{id}/events
it always get the result not found error
Anything I missed out on this?
