Trigger a pipeline on a monthly basis in Azure DevOps

Question

I want to create a pipeline that triggers every month even if there is a change in the git branch. This is what I currently have:

trigger: none
# YAML file in the main branch
schedules:
- cron: "0 0 1 * *"
  displayName: Monthly build
  branches:
    include:
    - master
    - development
  always: true

But this doesn't work. How can I make it work?
