Not Working

[ssgnoe]

No Chance to get this Repo working. I'm not able to make a composer update:
on php 7.4.

Problem 1
    - Root composer.json requires beyondcode/laravel-websockets dev-master -> satisfiable by beyondcode/laravel-websockets[dev-master].

    - Conclusion: don't install laravel/framework v5.7.0 (conflict analysis result)
    - beyondcode/laravel-websockets dev-master requires illuminate/support ^6.3|^7.0|^8.0 -> satisfiable by illuminate/support[v6.3.0, ..., 6.x-dev, v7.0.0, ..., 7.x-dev, v8.0.0, ..., 8.x-dev].
    - Only one of these can be installed: illuminate/support[v5.1.1, ..., 5.8.x-dev, v6.0.0, ..., 6.x-dev, v7.0.0, ..., 7.x-dev, v8.0.0, ..., 8.x-dev], laravel/framework[v5.7.0, ..., 5.7.x-dev]. laravel/framework replaces illuminate/support and thus cannot coexist with it.
    - Root composer.json requires laravel/framework 5.7.* -> satisfiable by laravel/framework[v5.7.0, ..., 5.7.x-dev].

Damn...
Ok, the problem solved by composer install, instead of composer update.
The package needs an Upgrade, so that it works with composer 2
