Script executed automatically on a date

Hello everybody,

I have a small script that returns to me in a field a date on which I must send an email. I created a button to send the email via Integromat.

This all works perfectly. What I would like is for the email to be sent automatically when the date is reached
In other words, I would like the Integromat script to be executed on the date.

I can't find the function that allows you to perform this type of automation.

Thank you for your answers
