Github Actions matrix questions

Question

I just want it to run in Matrix for both INT,STG environments, and for each env I need the longer name (integration,staging).

Does this thing possible within github actions? did I miss something in the sytanx? I tried looking around for it and couldn't find it..

Test:
 name: Deploy Test
 runs-on: ${{matrix.env}}
 strategy:
 matrix:
 env: [int, stg]
 needs: 
      - 'jobA'
      - 'jobB'

 steps:
    - name: Create test things.
 env: 
 ENVIRONMENT: 'if github.runs-on == int; then $ENVIRONMENT=integration else $ENVIRONMENT=staging' 
    - name: Test
 run: |
           some command using ${{env.ENVIRONMENT}} 
          - Desired output is integration

           some command using ${{env.ENVIRONMENT}}
          - Desired output is staging

Thanks for anyone willing to assist!
