Sending notification according to user group in Django Channels

Question

I have implemented a notifications functionality in my app where a notification is sent out to employees whenever a new customer is created. The problem I face is that the employees belong to different user groups. I would like to have only one user group, i.e., managers to receive the notification when the new customer is created. All other user groups, 'sales', 'customer service' should not receive that notification. How do you suggest I go about this given I am new to using Django Channels.

Thank you
