Failing to remove inactive deployments

[KD-7]

I am trying to remove the inactive deployments when I had previously deployed to github-pages.
See:

1. https://docs.github.com/en/rest/deployments/deployments?apiVersion=2022-11-28
2. https://docs.github.com/en/rest/deployments/deployments?apiVersion=2022-11-28#delete-a-deployment

(Note I have gh installed)

By first running via the GitHub CLI api

gh api \
  -H "Accept: application/vnd.github+json" \
  /repos/comp0016-group1/truelearn/deployments

To list out the deployment IDs then:

gh api \
  --method DELETE \
  -H "Accept: application/vnd.github+json" \
  /repos/comp0016-group1/truelearn/deployments/DEPLOYMENT_ID

But I get back the message:

{
  "message": "Not Found",
  "documentation_url": "https://docs.github.com/rest"
}
gh: Not Found (HTTP 404)

The reason why, is that I did not have organisation permission to do this. Hence I had to create a github app with organisation perms, to then generate a token which I used in a workflow to delete these deployments.
