Hi, I am trying to connect my go app to the spicedb instance through grpc. If I do insecurebeartoken, it will show

grpc: no transport security set (use grpc.WithInsecure() explicitly or set credentials)

and if I do securebeartoken with systemcerts it will show

error: desc = "transport: authentication handshake failed: tls: first record does not look like a TLS handshake"

when I try to add a relation. Can I get some help on this? Thank you!
