I would like ProtonMail to send to another email address a summary (object, from, date/hour) of new emails to another email address.

ProtonMail is blocked on my professional computer, as any other Email system, because the only authorized one is the institution's one (because cybersecurity). ProtonMail is my "stable" professional address (since I will not always be there, had happened once). To know that I have new emails here, I have rerouted all my emails to this authorized mail. This is overkill, since I will never answer them outside from proton. So a simple hourly, daily or more summary email of new messages would be great.
