Azure DevOps - configuring two jobs in yaml one with cron schedule second with manual execution

Question

I want to run the  e2e tests automatically at scheduled times and also on-demand. How can I achieve this?
 

jobs:
  - job: 'auto-run tests'
    displayName: E2E scheduled tests
    schedules:
      - cron: "0 5 * * 1,3,5"
        branches:
          include:
            - master
    steps:

<some auto-run tests job config here>

  - job: 'manually run tests'
    displayName: E2E manually run tests
    steps:
 

I tried this but, it didn't work. Can someone mention a solution to achieve this?
