Retrieving the all the users information from Azure Subscription

I want to retrieve all the user information from Subscription. We can get all the user list from an Azure subscription using below article.

https://docs.microsoft.com/en-us/rest/api/authorization/roleassignments/list

But above URl retrieves list of all User GUIDs(and some more information) but here i want user display name, mailid, etc.

Please help me How can i do this.

We can send this user GUIDs to graph API to retrieve the User information but it needs consent from Tenant admin and also we need two more extra calls(one is to get Graph bearer access token and other is call to actual graph api with above list of User GUIDs). So how can i do this with out graph API.
