gRPC testing - basic info

Hi,

I'm working on ReadyAPI 3.40.1 and can see that it support gRPC testing. Can anybody explain how to use it? I'll try "Import API definition" from API menu and select simple proto file as below (and others proto files found in Internet):

syntax = "proto3";
package tutorial;

message Greet {
string greeting = 1;
string username = 2;
}

but Ready API says always "Failed to import definition".

Or any .proto file that works? I'll try to use .proto and gRPC testing but now it's hard to start.

In logs I can see:
