Zia (Chatbot) not working in Chat in the ASAP React Native SDK

Hi. I created a basic POC app using the ASAP React Native SDK (react-native-zohodesk-portal-sdk), the official sample app (Zoho-Desk-ASAP-React-Native-sample), and following the Working with the ASAP SDK for React Native guide.

Chat is not enabled in my Zoho Desk dashboard (Setup → Channels → Chat). Zia is enabled (Setup → General → Zia).

I created a Mobile Add-On (Setup → Channels → ASAP → Mobile) with Chat and Zia enabled (the Chat settings are available in the Add-On creation window with Zia as the only option).

When I try to launch the Chat (ZDPortalChat.show()) in the React Native application (on iOS), "nothing happens". No logs are printed (logs are enabled: ZohoDeskPortalSDK.enableLogs()). The app is properly configured because I can launch other screens (KB for example) showing my account information.

If I do the same in a Web Add-On (Setup → Channels → ASAP → Web), it immediately works (the chat window works and Zia greets).

If I enable Chat in Zoho Desk (Setup → Channels → Chat) and in the Add-On, the Chat window now shows up in React Native (ZDPortalChat.show()) but the Chat messages are received by Zoho Desk agents, not by Zia.

Is there something else that I should do to get Zia working on the React Native chat?

Thank you very much.
