The warning message No gRPC protection active, consider launching with the -grpc-use-jwt flag indicates that the gRPC traffic between the emulator and the host machine is not secure. By default, gRPC traffic is not encrypted or authenticated, which can be a security risk.
To address this warning, you can launch the emulator with the -grpc-use-jwt flag, which enables JSON Web Token (JWT) authentication for gRPC traffic. JWT is a widely used open standard for securely transmitting information between parties.
