Outgoing WebHook issue in Microsoft Teams Channel

Hi Team,

Currently am using Outgoing web-hook for fetching the incoming messages in Microsoft Teams Channel.

I have created a sample console application in C# Dot Net and also created one Outgoing web-hook in teams channel. My problem is, I can't receive message without mentioning Outgoing web-hook name. In this particular Team Channel, 2 members are there. I can't receive their messages through my console application.

Anybody please suggest a proper solution.

Thanks in advance!!
