For operational instructions please see the template's overview: https://railway.app/template/fwH-l3#railway-cron-but-better

the bookmarklet doesnt work, cant get the schedule variable
Can you give the format of the schedule variable ie: something like {service_id}{cron_string}? -- this will also work

serviceID=${serviceID}&projectID=${projectID}&environmentID=${environmentID}&action=${action}&expression=${expression}

I'll check to see if the bookmarklet does work and fix it if need be.

Edit, the cron config bookmarklet works as intended without any changes.
