Hi @Jaya_Banbah ,
The above problem could be solved, if you make the volunteers as agents and use raise ticket actions node, so when a person ask for an help, you could connect to an agent and if he is not willing to do that, they could transfer to some other.
But apart from this solution, when an person asks for help and if you want to send those message to volunteers that would be possible, but mapping the response back to users would be difficult.
Since if its whatsapp, whatsapp session may expire after 24 hours, so if you wish to send the response back, you may need an whatsapp notification template…inorder to send the response back to user.
Please let us know incase of any queries.
