Unknown step_name "submit_phone" for USERNAME

[Altimis]

Hello community. I'm wondering if this challenge's handler is implemented yet ? I already have challenge_code_handler implemented, but I don't think it could handle this one. Thank you in advance.

Error :

Unknown step_name "submit_phone" for "USERNAME" in challenge resolver: {'step_name': 'submit_phone', 'step_data': {'phone_number': 'PHONE_NUMBER', 'show_whatsapp_otp_choice': True, 'whatsapp': False}, 'flow_render_type': 3, 'bloks_action': 'com.instagram.challenge.navigation.take_challenge', 'cni': XXXXXXXXX, 'challenge_context': 'Af5T0oIqMz9GtatrwOuVrjq85Pv23PFMyXw3eVT4XpwMxvaCT-jtpi7GdIjzSG5AJQyCJr_EPFqCYw5b-3JxRjk7wsu1HGlFR7aknJKerX9dvV2Jbrxfv-kE8r4UbGi7-Ept9Ryx9LHja55E7C3NjBR4RJ5dOI37HgutdNRmbmEiir-Rzgm1UNvwy4RoFFWqKKEXdWn7QAQCfPNsOzq1UdBvyxzse4BreOZPVMAUlcRw', 'challenge_type_enum_str': 'SMS', 'status': 'ok'}
