It’s ridiculous, but they have recently introduced a feature to change the list of messages, so you can just set it to Working or similar now:
"spinnerVerbs": {
"mode": "replace",
"verbs": ["Working"]
}

Anthropic is mocking developers here :)
They bothered to let you override default nonsense messages with custom messages, but they still don't want to let you see what you are actually interested in. The actual information is kept hidden.
Luckily, new open weight models from China caught up with Anthropic, so you can use a sane harness with a much cheaper subscription and never look back.
