The useful handoff is early enough that the customer is not repeating themselves, and late enough that the person joining already has the answers.
Decide the stop rules in advance
Price exceptions, complaints, and a direct request for a human should leave the agent immediately. Routine questions about hours, location and a first qualification can stay with it.
Write those rules in the same words your team uses, in Arabic or English.
Pass the thread, not a summary in another app
The person who joins should see the chat, the answers and who owns it next. Assigning the lead inside WapiNEXA keeps that context on the company number.
