Grant it to an app
In the portal: App registrations › your app › API permissions › Add a permission › Microsoft Graph › Application permissions, then grant admin consent. Or with Graph PowerShell:
Connect-MgGraph -Scopes "Application.Read.All", "AppRoleAssignment.ReadWrite.All"
$graph = Get-MgServicePrincipal -Filter "appId eq '00000003-0000-0000-c000-000000000000'"
$app = Get-MgServicePrincipal -Filter "appId eq '<your app's client id>'"
New-MgServicePrincipalAppRoleAssignment -ServicePrincipalId $app.Id `
-PrincipalId $app.Id -ResourceId $graph.Id -AppRoleId "f529a223-ea70-43ec-b268-5012de2fbaa2"Ask for it when signing in
Delegated permissions act as the signed-in user, so the app can never do more than that user can.
