NAC Component workflow Input variables mandatory

All,

I am developing a component workflow and will call this workflow from another workflow for SharePoint online.  I have created 4 input variable/parameters inside the component workflow.  I want to make sure that these parameters must be passed to component workflow when calling from another workflow.  I don’t see any setting/configuration where I can declare the input parameters as “REQUIRED” or “MANDATORY”.  Do anyone know how if this can be done?

Thank you
