Publish Angular App Alongside Web API to Azure

I created an ASP.NET Core app with Angular as instructed via this guide. I'm publishing it to Azure using the GitHub Action support, which was generated by Azure and then I modified to get it to work. I've got it working for my app but only the API seems to publish, and at the designated endpoint URLs. This makes sense since I had to modify the workflow to indicate the API project directly. How can I publish the Angular app (in the UI project) to Azure as well with this same workflow?

Here is the repo for reference: https://github.com/rarDevelopment/rardk-web-dotnet The workflow: https://github.com/rarDevelopment/rardk-web-dotnet/blob/main/.github/workflows/main_rardkweb.yml and the API sample endpoint can be seen running here: https://rardkweb.azurewebsites.net/WeatherForecast
