How to schedule a job to run once at a specific time

Hello,

I have an application that sends email campaigns to customers at a scheduled time. I’m trying to leverage on Hangfire’s job queue. I’m trying to set the time a job should run from the forntend for example, A campaign should run on the 22nd of October just once and another job can be scheduled to run on the 24th of November. How do I set the scheduled time from user input on hangfire.

Thank you.
