Automation creation help

I want to create an automation that runs on the 2nd and 17th of every month to send each employee a personalized view of their reimbursed expenses that were marked paid for the day before payroll (if they had any). I want to send a link to a view that will only show the expenses that meet that criteria. The link should not be structured in a way that would allow an employee to change something in the URL to see other employee’s expenses.
