How to set up and distribute, and retrieve a multiple signature form

I am working on a three-part fillable scholarship form that student applicants, a parent or guardian if the applicant is not 18, and a teacher or counselor will complete and sign electronically to submit. So the final document must be submitted with at least two and maybe three electronic signatures. I will create the form in InDesign 2025.

Other than electronically signing an pdf I am without a clue as to how this is set up. I will use InDesign to set up the form. Should the instructions flow from the student to parents if necessary, to teacher/counselor then back to the student-applicant for submission? Or what? Should we have separate teacher/counselor form?

Thanks to those who know more than me,

Joe
