BuddyPress plugin, display group feed on any page with shortcode

Hi, we are building a BuddyBoss (BudyPress) website and I need help with building up a plugin that will allow me to display a group feed (not activity) into any page via shortcode or widget.

There is a similar plugin out there that displays the group activity, but that doesn't allow people to post, only read the latest posts. https://buddydev.com/plugins/bp-activity-shortcode/

I need this to be developed quite soon, before Wednesday the 4th.

Thanks
Deborah
