This post is meant for users who are trying to utilize the Microsoft Graph Explorer but are getting an error regarding admin consent. This error is described in the picture below :
Giving Consent for All Users for Microsoft Graph Explorer
This error is occurring because the user trying to use the graph explorer is trying to utilize a v2 permission that requires admin consent. The permissions/scopes regarding the v2 endpoint are described in the link here : https://docs.microsoft.com/en-us/azure/active-directory/develop/active-directory-v2-scopes
To resolve this issue, the Microsoft Graph explorer provides a convenient pre-developed URL for users to give the Global Admin of the tenant in order to grant admin consent on behalf of all users in the tenant. This is currently the only way to let users use the Microsoft Graph Explorer to get access to the Microsoft Graph API with permissions that require Admin Consent.
