Is it possible to test the Multiplay-SDK locally in the editor? I mean the events like Allocate, Deallocate. When I try to run my game in the editor I get the following error: "InvalidOperationException: Failed to load ServerConfig. Ensure there is a test server.json file available in the project directory" I couldn't find a server.json file for testing in the docs. Am I missing something or is this not possible?
