TaskRequest.Payload

I have some questions about the task submission process.
1. When I run `devkit avs call` , is it calling `TaskMailBox` contract?
2. why in the example on website, the call is `devkit avs call -- signature="(uint256,string)" args='(5,"hello")'` , while `HelloWorld.sol` functions take as input only a string?

3. I am going through the hourglass template, and in cmd/main.go I see `HandleTask` function, with input `t *performerV1.TaskRequest`, which is defined as
```
type TaskRequest struct {
state protoimpl.MessageState
sizeCache protoimpl.SizeCache
unknownFields protoimpl.UnknownFields

TaskId []byte `protobuf:"bytes,1,opt,name=task_id,json=taskId,proto3" json:"task_id,omitempty"`
Payload []byte `protobuf:"bytes,2,opt,name=payload,proto3" json:"payload,omitempty"`
}
```
from what I see, Payload is Abi encoded, for the example on the github with hello world, this is abi encoding of (5, "hello") arguments?

4. And does anyone has a sample go function that actually does something (like squaring a number) and return it? It would be helpful for me.

Commencez par HandleTask de cmd/main.go, le modèle hourglass et l’exemple d’appel devkit avs référencé dans l’issue. Suivez l’utilisation de TaskRequest.Payload et comparez les entrées documentées de HelloWorld.sol avec l’exemple de signature de la CLI. Le travail est terminé lorsque le flux de soumission et le payload ABI sont expliqués et qu’un exemple Go fonctionnel pour un calcul simple est inclus.
