Motivation

Reviewer checklist

• [ ] If this PR modifies anything else than strictly the default scenario, then remove the run-default-scenario label
• [ ] CI is green
  • [ ] If not, failing jobs are not related to this change (and you are 100% sure about this statement)

Workflow

1. ⚠️⚠️ Create your PR as draft
2. Follow the style guidelines of this project (See how to easily lint the code)
3. Work on you PR until the CI passes (if something not related to your task is failing, you can ignore it)
4. Mark it as ready for review

NOTE: By default in PR only default scenario tests will be launched. Remove the run-default-scenario label to run all scenarios (more info)

Once your PR is reviewed, you can merge it! :heart:
