Activity log from admin panel

Hello community, I’m testing nextcloud for my company. I’m using the latest version (12.0.3,) and I’m in trouble with the activity log.
From admin panel I need to have the log of every operation made by other user (like sharing, deleted files, uploading…etc).
Under activities , from other, I cannot see nothing of other users, but just operation done with my shared link.
I enable the app Activities for shared file downloads and I enabled it via CLI sudo -u www-data ./occ app:enable admin_audit
also cannot see this kin of log in nextcloud.log I can see login failed entries but not file activities.
do you have any suggestion?
Kind regards,
