TCP packets with Protobuf messages not dissected

I’m trying to use Wireshark to dissect Protobuf messages sent over TCP using gRPC. When I view the data portion of a messages, I see raw bytes instead of a dissected view.

I’ve added the path to the directory containing the Protobuf file in Preferences->Protocols->Protobuf->Protobuf search paths. I’ve checked “Load .proto files on startup.”

In Analyze->Available protocols, Protobuf is selected.

When I go to Analyze->Decode as.. and add my port number, I don’t see a way to choose Protobuf in Current column.

I’m using Wireshark on macOS.
