Workflow instructions not followed when deploying Azure web app via github

Question

I am using GitHub to deploy a streamlit app into Azure web app. I discovered the workflow file that is created under the .github/workflows folder as part of the CI/CD pipeline.

In it, I modified it to add some extra commands to upgrade pip and install wheel before the dependencies. But when deploying to Azure web app it doesn't follow it.

Is it Azure or am I missing out on something here? (I commented out the install for libgl)

Here is my workflow file:

I tried deploying Streamlit app in Azure with Github Actions and it was successful.

There are certain pre-requisites that you need to follow before deploying Streamlit app, Refer below:-

According to my SO answer

1) For streamlit to work, Create Azure Web app with Runtime set to 3.10 and above, With SKU set to B1.

enter image description here

2) In the Settings of Azure Web app > Configuration> General Settings > Select HTTPS Only to OFF > And add the startup command below( you can add this startup command later after the deployment from github actions and load your website again):-

enter image description here

python -m streamlit run app.py --server.port 8000 --server.address 0.0.0.0

enter image description here

Even if you keep HTTPS only to Off you can browse your website with Https.

3) Then I selected Deployment Center connected to my Github repository and started the deployment like below:-

When I clicked Save, The github action deployment got triggered in my github repository:-

          python -m venv venv
          source venv/bin/activate

        uses: actions/upload-artifact@v2
        with:

          path: |
            . 
            !venv/
  deploy:
    runs-on: ubuntu-latest
    needs: build
    environment:

      url: ${{ steps.deploy-to-webapp.outputs.webapp-url }}

    steps:

        uses: azure/webapps-deploy@v2
        id: deploy-to-webapp
        with:
          app-name: 'valleywebapp98'
          slot-name: 'Production'
          publish-profile: ${{ secrets.AZUREAPPSERVICE_PUBLISHPROFILE_CCB79104830649D193337DBF9ABC1AE9 }}

Output:-

My streamlit app works fine. Its deployed in B3 with Python 3.10. The problem its it doesn't follow the instructions described in the CI/CD workflow.
Specifically the instruction to update pip and previously when libgl installation was uncommented, even that instruction.
