Simple request

Dear Bonitasoft,

I am using bonitasoft community 6.2.6 for workflow. I have a simple request.

I create a admin form. Inside is a dropdown list of users (user1, user2, user3).

The next task maps to a group which has team member user1, user2, user3

My question is :
How do i use actor filter on the next task so that when an admin select user1 from list, only user1 will be assigned.
