Activity on folders shows nothing but "created"

Hi ! I can see activities at file level, but the activity tab for folders doesn’t show anything but the “Created <folder_name>”, both shared and non-shared folders. I understand that for shared folders I should enable a parameter in the config file, but what about non-shared folders? Do you confirm that it’s by clicking on the three dots at folder level and opening the Activity tab that we’re supposed to see the activity related to this folder?

For instance, my Main Notebook folder in Notes (used by the Notes app) which should be full of activities, is empty.
