Server&Client&Migration

Hello everyone. Has anyone used the Host Migration System Host Migration System in Code Plugins - UE Marketplace (is it worth taking it)? In general, I need it to be like in cs 1.6. So that anyone who wished could be a server and clients connected to it and in cases of leaving the server, migration took place and any of the clients could become a server (on request or automatically). Both online and locally. So that there is no dependence on servers. For example, I don’t like how in Fortnite and similar games, servers don’t work and you can’t go into the game and you can’t play. Are there any implementations in the marketplace or what can you suggest, advise?
