	<brief_description>
		Class that can be inherited to implement custom multiplayer API networking layers via GDExtension.
	</brief_description>
	<description>
		This class is designed to be inherited from a GDExtension plugin to implement custom networking layers for the multiplayer API (such as WebRTC). All the methods below [b]must[/b] be implemented to have a working custom multiplayer implementation. See also [MultiplayerAPI].
