+
+1. Add `chat_id` or `token` to channels in `config/logging.php`.  Overrides `config('telegram.chat_id')`.
+```php
+[
+    'channels' => [
+        [
+            'company' => [
+                'driver' => 'custom',
+                'via' => TelegramLogger::class,
+                'chat_id' => env('TELEGRAM_COMPANY_CHAT_ID'),
+                'token' => env('TELEGRAM_COMPANY_BOT_TOKEN')
