According to the package dependencies listed at https://packagist.org/packages/brozot/laravel-fcm (and according to the message you've posted), this package requires Monolog in v1, but currently you have Monolog installed in v2.
To resolve this, you should either ask the package maintainer whether the package could support the most recent version of Monolog (which is already listed as a bug report in https://github.com/brozot/Laravel-FCM/issues/152), or you downgrade your installed version to v1. But according to that bug report, I'd assume that the package is not compatible with Laravel 6 yet
