How do I order units to do something using raw interface?

For example, I have this code:
```python
for drone in units["Drones"]:
order = rawpb.UnitOrder(target_unit_tag = my_own_hatchery.tag, ability_id = 3674)
# drone.orders.add(order) <--- this line states that I'm providing two arguments
drone.orders.extend([order]) # adds order to the list but this doesn't affect the drones
```
This supposed to force the drones to attack their own hatchery, but instead of that units do not follow the order I've issued, and if I provide an order using ```drone.orders.add(order)``` it will state that I'm providing two arguments instead of required one.

And ofc rawpb is just raw_pb2 from s2clientprotocol
As well as to get all the units one should issue this line of code:
```controller.observe().observation.raw_data.units```

Start with the raw_pb2 UnitOrder definition and the drone.orders usage shown in the issue. Reproduce the behavior through controller.observe().observation.raw_data.units, then trace how orders are represented and submitted. Done means the correct raw-interface ordering behavior is established and the issue's usage or documentation is clarified.
