getConfig(string|null $key = null, mixed $default = null) : mixed
Returns the config.
Reading the whole config:
$this->getConfig();
Reading a specific value:
$this->getConfig('key');
Reading a nested value:
$this->getConfig('some.nested.key');
Reading with default value:

configShallow(string|array $key, mixed|null $value = null) : $this
Merge provided config with existing config. Unlike `config()` which does a recursive merge for nested keys, this method does a simple merge.
Setting a specific value:
$this->configShallow('key', $value);
Setting a nested value:
$this->configShallow('some.nested.key', $value);
Updating multiple config settings at the same time:
$this->configShallow(['one' => 'value', 'another' => 'value']);
