Matomo email report scheduler

Anyone who can explain the logic of the email report scheduling in Matomo?
Or is there a documentation of the functions connection with the API? (How persistent is the api-call? (Does it adjust the future reports?)

Here you can finde some informations: https://matomo.org/guide/manage-matomo/email-reports/

A few examples using the API:
