I have a YAML pipeline that I want to run, but I can't work out how to tell GitHub to use my file and stop it from creating a new one.

The yaml file is in .github/workflows in my develop branch.

In GitHub, under Actions, if I click "set up a workflow yourself" it takes me to:

The path is correct but it's defaulting to the default master branch and clicking on master just takes me to the code view. I can't find a way to change it to develop

I believe the relevant part of the code is:

name: CI

# Controls when the action will run.
on:
  # Triggers the workflow on push or pull request events but only for the main branch
  push:
    branches: [ master ]

  # Allows you to run this workflow manually from the Actions tab
  workflow_dispatch:

If I understand this correctly, workflow_dispatch should allow it to be run manually, but it doesn't appear to be listed.

I'm sure this is 101, but I can't work it out. If anyone has any ideas, I'd be grateful if you could share them, please.
