Not working and in code bags.

This is my first time using OAuth, I don't understand this protocol. But I see obvious errors in the code.
Probably the cat walked on the keyboard when they wrote this class. :-)

Please give a practical description of this library in README.md.
Sample code for how to use this class.
Please give an example code for easy use, without using inheritance. So that the developer can declare the object and set options for it.

There are no examples of using this library on the Internet at all. Please write the simplest example in the document README.md.

The code used the HttpFactory class before.
The code specifies the \Joomla\Http\HttpFactory namespace ;
But the CMS has the same HttpFactory class from the \Joomla\CMS\Http\HttpFactory namespace;
Maybe in the OAuth 2 HttpFactory from another space? Since there is just a static method.
The HttpFactory class has static methods in a different namespace.

In the test assembly, you specified the arguments in the class __constructor()
$options = array(),
Compatibility with PHP 7.4 does not allow you to specify default values ahead of other arguments.

	public function __construct(
		$options = array(),
		Http $http,
		Input $input,
		AbstractWebApplication $application = null
	) {
		$this->options     = $options;
		$this->http        = $http;
		$this->input       = $input;
		$this->application = $application;
	}
