github actions create release via API

Question

Here is a github workflow that I would like to use to create a release.

name: make release

on: 
  workflow_dispatch:


jobs:
  try-to-create-a-tag:
    runs-on: ubuntu-latest
      
    steps:
      - name: Create release
        run: curl \
               -X POST \
               -H "Accept:application/vnd.github+json" \
               -H "Authorization:token ${ secrets.GITHUB_TOKEN }" \
               https://api.github.com/repos/.../releases \
               -d '{"tag_name":"tag_test11","target_commitish":"main","name":"tag_test11","body":"Description of the release","draft":false,"prerelease":false,"generate_release_notes":false}'

The workflow runs without error, however I get the following message from curl:
authorization:token ${ secrets.GITHUB_TOKEN }: bad substitution

I have also tried using double braces, however this didn't work either. How can I substitute the variable into the curl command?

NOTE: the error is that one must use a | right after run: when splitting over multiple lines.

You have to use double brackets: ${{ secrets.GITHUB_TOKEN }}
