I'm trying to utilize slack incoming webhooks to let my teammates know the information of new hires written in sheet at the designated time.
At 3rd column, I write the first date of each new hire. And want to share info of new hires a week before the first date, at certain time.
For example, if there are 3 new hires on 2nd Monday of August, I'd like to let slack bot share the info at 1st Monday of August, 10:00am KST.
Looks like I need to use formatted_date value to send out auto message a week earlier. How would I make it possible?
