Redirect to different page based on permission in nintex form

Is it possible to redirect user to different page, when trying to access others forms ?

I am trying to achieve a condition 'if employee is not equal to current user and if employee is not part of a SharePoint group(this will be Approvers), should redirect to different page'. Typically no one should have the access, once the form is submitted other than the Approver and current user. Is this possible in nintex forms?

Please advice me how to proceed on this? 

Thanks in advance.
