Hi everyone, I'm trying to update the additional voice settings for my assistant, such as Background Sound and Backchanneling Enabled, using the PATCH API at https://api.vapi.ai/assistant/{id}. However, I'm unsure about which specific ID is required in the {id} parameter. It doesn't seem to be the phone ID, agent ID, or org ID. Could anyone clarify what kind of ID this API is expecting for updating these voice configurations? Thank you in advance for your help!
