You ca use the az command line tool and the built-in Access Token, when you need to trigger a pipeline inside Azure DevOps on the same Organization.

- job:
  displayName: "Run Pipeline"
  steps:
  - bash: |
      az pipelines run --project 'PROJECT' --id 123456 --branch 'main' 
    displayName: 'Trigger Pipeline 123456'
    env:
      AZURE_DEVOPS_EXT_PAT: $(System.AccessToken)

az pipelines run can also set parameters for a pipeline you want to trigger:
az pipelines run --project 'PROJECT' --id 123456 --branch 'main' --parameters 'param1=VALUE'
(The ones when you click "Run Pipeline" and can set/select in the UI in the Browser)
