Access HTTP2 headers from a @grpc/grpc-js Handler

I have a @grpc/grpc-js server. It includes a handler for a method that looks like this

server = new grpc.Server()
server.addService(proto.GrpcTester.service, {
    myMethod(call, callback) {
       callback(null, {hello:"world"})
    }
})

Is there a way to access the HTTP2 request headers that were set when this request was made?
