How to check PR reviewer name

I have a workflow that is triggered by a pull request review being submitted
i.e.

on:
    pull_request_review:
        types: [submitted]
jobs:
    job1:
        steps:
            - name: run command1 if approved by person1
               if: github.event.review.state == 'approved' # by person1
               run: #something
            - name: run command2 if approved by person2
               if: github.event.review.state == 'approved' # by person2
               run: #something else
            - name: run command3 if approved by person1 and person2
               if: github.event.review.state == 'approved' # by person 1 and also by person2
               run: #something different

I need to conditionally run different steps depending on who has approved the PR. Is there a way to do this? Perhaps check the username of some other identifer of the PR approver(s)?
