I have added an action row link to users.php so that when its clicked it links to a list table.
To generate the data for the clicked user in my custom list table, I need to capture the user ID.
I have all the code working but I don't know how to access the user ID of the user that was clicked.
I am passing the user ID as user via the link so its show in my custom list table url. For example, admin.php?page=history_logger&user=3.
