Benoit_Fournier Unfortunately, this feature is specific to SharePoint lists and Microsoft Lists only. This feature is not available for document libraries.
If you want Microsoft to implement this feature for document libraries as well, you can provide your feedback/idea at: SharePoint Feedback Portal
Additional: It is possible to add comments and mention other users inside word documents as well: Insert or delete a comment
