BPF - If Owner of Activity is a team, how to find user who completed the activity?

Dear all,

If the OWNER property of the ENTITY dimension is assigned as a Team of Users, How do we find the user who completed the activity. As per my understanding,

- We are able to see the Team's name only in the Process Monitor.

- Only If we enable E-mail notification, all the team members are able to get the mail with the user name who completed the task.

Please let me know any other option available to find this? Any tables that can be read.

I'm not sure of the uses of BPF BADI. Please let me know, if that will be of any help.

Thanks & Regards
