Receive a HTTP request for all messages in a Skype group conversation with an Azure Bot

Question

I have a working Skype bot working via the Azure Bot. In Azure, under Resource > Configuration, the bot is configured to send incoming messages to a "Messaging endpoint".

This works well for 1:1 messages, and bot mentions (with @) in a group. However I want to get a webhook request for all messages where the bot is added, even when it is not mentioned.

Is this possible?

I found some documentation on how to do this in Microsoft Teams, but I am not sure how to do it in Skype:

https://learn.microsoft.com/en-us/microsoftteams/platform/bots/how-to/conversations/channel-messages-with-rsc?tabs=channel%2Cdotnet

I have also found this thread that basically says that is not possible, not sure if it is still relevant:
