Hi @Tarun Gupta ,
According to my research and testing, if you want to set permissions for Microsoft Graph, please register your app at the Azure app registration portal, and then configure permissions for Microsoft Graph, at last get administrator consent. Please refer to the specific steps in the document to configure permissions: https://learn.microsoft.com/en-us/graph/auth-v2-service#authentication-and-authorization-steps
More information for reference: Microsoft Graph permissions reference
Hope it can help you. Thanks for your understanding.
