Generate mail notification for each Nextcloud users


May someone tell me if my request is possible with Nextcloud ?

I would like generate email notification for each nextcloud users (or nextcloud groups users) when a new files are added in shared folder.
This folder is shared with a group.
By example, to send by email personnal link for each user to retrieve pay sheet each month…
The access could be protected by individual password.

I am newbie with Nextcloud, but maybe for Nextcloud expert, this is not a complex task ?

Best Regards,
