How to put a comment or a “call in a month” timer on an incoming lead?

Question

Bitrix24

A person sends an application from the site, it arrives at bitrix24, we, in turn, send him a link to demo access to the product.
In a month, we need to call the client and sell a paid one or extend a free plan.
How to hang an event or a timer with a backlight “call in a month” on an incoming lead?
