Can't get Voice Assistant Config with aioesphomeapi

Also posted here, not sure where it fits best.

I am trying to get my Home Assistant Voice Preview settings using aioesphomeapi, but I get an "empty" result.

Code to repro:

import aioesphomeapi

api = aioesphomeapi.APIClient("<My IP>", 6053, "")
await api.connect(login=True)

config = await api.get_voice_assistant_configuration(10)
print(config)

Result:
VoiceAssistantConfigurationResponse(available_wake_words=[], active_wake_words=[], max_active_wake_words=0)

The Voice Assistant works, I can change wake word using Home Assistant.
I am using aioesphomeapi==28.0.0.

Any ideas on how to debug this further?
