Hi @Morgy93. Thank you for your contribution
Here is some useful tips how you can test your changes using Magento test environment.
Add the comment under your pull request to deploy test or vanilla Magento instance:

• @magento give me test instance - deploy test instance based on PR changes
• @magento give me 2.4-develop instance - deploy vanilla Magento instance

❗ Automated tests can be triggered manually with an appropriate comment:

• @magento run all tests - run or re-run all required tests against the PR changes
• @magento run <test-build(s)> - run or re-run specific test build(s)
  For example: @magento run Unit Tests

<test-build(s)> is a comma-separated list of build names. Allowed build names are:

1. Database Compare
2. Functional Tests CE
3. Functional Tests EE,
4. Functional Tests B2B
5. Integration Tests
6. Magento Health Index
7. Sample Data Tests CE
8. Sample Data Tests EE
9. Sample Data Tests B2B
10. Static Tests
11. Unit Tests
12. WebAPI Tests

You can find more information about the builds here

ℹ️ Please run only needed test builds instead of all when developing. Please run all test builds before sending your PR for review.

For more details, please, review the Magento Contributor Guide documentation.

I don't know why, but it said I need to reopen the pull request, weird. 🤷

@sidolov @gabrieldagama could you help with PR reopening? I also don’t have permissions to do so

[Morgy93]

Doesn't matter, I already opened up another one here: #30516

Thanks anyway for checking!
