Notification for non assigned requests after 1 business day


I have a SS that adds new rows from a form. As part of our workflow we want to send an alert using the automation builder if the request has not been assigned after 1 business day but need some help with setting up the triggers. I am assuming i need to use the created date column and a helper column to add 1 day but not sure of the next steps or how to create an IF statement using date time. Any help or guidance to articles to help would be appreciated.
