I have an issue when I try to install Laravel-FCM on Lumen 7.0.5 (Laravel component 7.0). After running this command:

sudo composer require brozot/laravel-fcm

I get a long list of errors. Some of them are:

Problem 1
    - Conclusion: don't install illuminate/support 6.x-dev
    - Conclusion: don't install brozot/laravel-fcm 1.3.1|install illuminate/support 6.x-dev

    - Conclusion: remove illuminate/contracts v7.6.2

Seems it needs to be updated to support laravel 7. See the progress on #175
