@ludovic35 Si ta PR est prête à être relue, retire l'état "draft". J'ai été notifié que tu voulais une revue, donc je m'attends naturellement à ce que la PR ne soit pas en draft.

Il faut aussi que tu synchronises (via rebase) ta branche avec develop qui a bougé depuis.

D'ailleurs tu n'as coché aucune case de ta PR ; or il y a une bonne partie que tu peux remplir ou remplacer par NA comme indiqué dans le template. On ne peut pas se permettre de devoir remettre d'équerre les PR de chacun ;)
