Hello, Are the dependents of 485 (Skilled Graduate) visa allowed to work? Kindly guide. Thanks Sai

Hi, I just got my 485 approved,and I want to sponsor my spouse. I've looked at the 485 application guidelines for adding family members. I downloaded the form-1276, but that form if really confusing because it's intended for onshore applicant so many of the details are completely irrelevant...
