Description of the problem, including code/CLI snippet

how did you implement the "from" parameter in the function :

activities = gl.user_activities.list(all=True, as_list=False, from='2018-01-01')

found in the API : https://docs.gitlab.com/ce/api/users.html#get-user-activities-admin-only

thank you
