Get users email without auth

[RabieAli95]

Hi, I'm trying to get my personal emails by your pkg, this is my code:

in .env :

MSGRAPH_CLIENT_ID=01306e60-4f2d-425cxxxxxxxxxx  // Application (client) ID from 'aad.portal.azure.com'
MSGRAPH_SECRET_ID=f3cb7221-4a86-468cxxxxxxxxxxx // Object ID  from 'aad.portal.azure.com'
MSGRAPH_TENANT_ID=9597912b-442e-4ce3xxxxxxxxxx // Directory (tenant) ID from 'aad.portal.azure.com'

Route::get('/', function () {
    $emails = MsGraph::getEmails();
    dd($emails);
});

I got error

Object of class Illuminate\Routing\Redirector could not be converted to string
