Answer: Yes, it is possible to create some forms of selection. The first would be that the attendant himself informs his codename (a kind of extension) to the customer, and whenever the customer wants to speak to that specific attendant, he may just call him by his codename on the company's own WhatsApp; Example: Attendant: Jose Silva, codename: @silva.
Another way would be to create a submenu in the department selected in the chatbot with the names of the salespeople; Example: 1-Andre, 2-Beto, 3-Carlos ... that way the client could choose who he wants to talk to.
It is also possible for the customers to have a database of all their contacts, and thus create an access via API, but it would be much more complex and laborious.
