Laravel Slack Notification Channel Issue

This repo demonstrates that we can't use the to() function using the Laravel Slack Notification Channel package to attempt to send a notification to "other" channels.

Setup

• Clone the repo and run composer update, and run migrations & seeder.
• Add SLACK_WEBHOOK_URL value in .env > point it to a webhook URL that is part of a slack app you own.
• Ensure the webhook URL does not point to #general
• In terminal, run php artisan test:go
• The notification that gets fired always sends the message to the "app" channel, and never the #general channel.
