TimeColumn
Specify the name of the input column that contains the click times.
The timestamp_column must also be an order_column.

ClickLag
[Optional] Specify the minimum number of seconds between clicks for the session user to be considered human. If clicks are more frequent, indicating that the user is a bot, the function ignores the session. The min_human_click_lag must be less than session_timout.
