Thank you all, it’s now available on the marketplace \o/ ! I’m currently adding support for 4.20 and 4.21, you can use the trick above (in the FAQ) to make it work on other versions than 4.22 in the meantime.
Don’t hesitate to give me some feedbacks on how to improve it.
EDIT: 4.20 and 4.21 versions are now in pending status
