Hello @bertrandda! Great, that looks awesome 
Another topic regarding the Caldav service. We were talking about it here → Point stabilité, mise à jour des dépendance & qualité de code, it would be cool if we could remove the « moment » dependency used in the Caldav service front-end, a dependency that is deprecated and quite heavy.
This is a topic independent of this PR of course, but we should look into it at some point
