Multiple pipelines with the same name

[mbpolan]

I have a GitHub Action that should trigger an Azure DevOps pipeline. In my project, I have multiple pipelines that have the same name, but are grouped under different folders by convention. For example:

+ my-app-1
  - deploy
+ my-app-2
  - deploy

In the above, my-app-1 and my-app-2 are folders corresponding to different repositories, and our standards are to have a deploy pipeline for each repository. I would like to trigger specific deploy pipelines using a GitHub Action.

- name: Azure Pipelines Action
  uses: Azure/pipelines@v1
  with:
    azure-devops-project-url: https://dev.azure.com/organization/project
    azure-pipeline-name: 'deploy'       # this is in question
    azure-devops-token: ${{ secrets.AZURE_DEVOPS_TOKEN }}

How would I configure the action to trigger the my-app-1/deploy pipeline specifically?

In the above snippet, if I specify deploy by itself, I get an error:
More than 1 Pipeline named "deploy" found in project "project"

If I try to prefix this with either my-app-1/deploy or my-app-1\deploy, I get a different error:
Failed request: (401)

The only way I'm able to get this to work is if I give each pipeline a unique name, but I'd prefer not to have to break my existing conventions to do this.
