If any account other than the admin calls the proxy, the call will be forwarded to the implementation, even if * that call matches one of the admin functions exposed by the proxy itself. * 2. If the admin calls the proxy, it can access the admin functions, but its calls will never be forwarded to the * implementation. If the admin tries to call a function on the implementation it will fail with an error that says * "admin cannot fallback to proxy target". * * These properties mean that the admin account can only be used for admin actions like upgrading the proxy or changing * the admin, so it's best if it's a dedicated account that is not used for anything else. This will avoid headaches due * to sudden errors when trying to call a function from the proxy implementation. * * Our recommendation is for the dedicated account to be an instance of the {ProxyAdmin} contract.
