How to enable receiving inbound messages in Leadsquared?

I have integrated Yellow with Leadsquared, added a template and then triggered a whatsapp through Leadsquared itself.
Now i am not receiving the replies of the whatsapp message on Leadsquared. How do i enable the system to send inbound messages to Leadsquared. There must be a Inbound webhook for that?

Please help

Any help document to understand how to get this?
