How to accept EULA for update with Powershell 4 on WSUS 2012 R2

I 've writen a powershell script that approve all security and critical update between to dates with Approve-wsusUpdate cmdlet witch is include on PS4 and WSUS 2012R2.

But there is no place in y script where I decide to accept the EULA if it's present.

Is it necessary to force EULA validation or not with last WSUS cmdlets?

If yes how to do this.
