Creation of a Viber bot with 3 roles

Order from the director of the agricultural company for the automation of the buying/selling process of grain products. Registration has been made for two roles: "Supplier" - sells grain, and "Driver" - transports grain products to the destination. Registration occurs with role selection, contact details are saved in a table, and then the user provides documents that are checked by AI and stored in the database. After that, functionalities are opened for them: for the driver "Working with routes," for the supplier "Selling grain products."
