I was wondering, can I just tell HR to put me back on payroll if I just have the approval confirmation on ELIS?

It says valid time 9/8/2016 to 9/7/2018 on my DACA approval letter, but I do not see any EAD approval letter even though it says that was approved also.

I don't want to let HR put me back on payroll and then 2 weeks later get my EAD card with it showing the starting date around 9/22/2016...
