Hello iagogv
Thanks for your interest in CryptPad.
However, due to the end-to-end encrypted (E2EE) nature of CryptPad, our server does not have access to the state of the form and thus cannot trigger actions based on that. The notification you can see in CryptPad is sent via the mailbox system and is triggered by the person answering the form toward form owners in an E2EE fashion.
Sorry for the negative answer to your feature request.
