I have made a group assignment, and I want to assign everyone in the class 3 groups' homework to do peer review. How does that work?

If I choose both "group assignment" and "peer review" when creating the homework, will everyone be assigned to groups or assigned to individual person when peer reviewing?

For example, Group 1 has student a,b and c, Group 2 has student d,e and f. After assigning peer review, student a's peer review will be Group2 or someone in Group 2 like d, or only the one who submitted to homework in Group 2?

Any suggestions would be helpful!
