You can use the azure ad connector from power apps but the user of the app will need to have permissions granted to them by an azure admin

also like any azure service the user of the app will need to have a full per apps or per user license for power apps. Just having the license tha comes with office 365 is not sufficient. My recommendation was a way to get around these requirements.
you can use the UpdateUser function to update a user’s active directory record from a power app. https://docs.microsoft.com/en-us/connectors/azuread/
use something like the following to update user record
AzureAD.UpdateUser(id,{userPrincipalName:Text,displayName:Text,mailNickname:Text,givenName:Text,surname:Text,accountEnabled:Boolean,jobTitle:Text,mobilePhone:Text,officeLocation:Text,preferedLanguage:Text,businessPhones:Table})
