Skype Bot Not Responding to Group Messages

[jojohanhannesnes]

I'm currently developing a bot using botbuilder, and I've successfully registered it on Azure with Skype as the channels. The bot is working fine in 1:1 conversations and with mentions in groups. However, I would like to explore the possibility of having the bot listen to every message sent in a group that it has joined.

Is this feasible? Should I be using a different handler (other than ActivityHandler), or are there other events apart from onMessage that I should consider for handling group messages?

Any insights or suggestions would be greatly appreciated. Thanks!
