Email Notification for new content dropped into existing shares for external users

Hello All
Is it possible that if we share a folder via email with someone (who doesn’t have a nextcloud user account on our server) to get further emails once more content has been put into that folder? Right now the external user does receive an email when we share a folder/file with them but we would like it to further notify them when new content is dropped into that share and not have to create new shares. This would allow us to not have to send an email for every shared folder/file which we want to send to someone when we are working on a project with them. We are running 14.0.3 right now.
I looked thru the support articles but didn’t find something that addressed this precisely.
Thank you
