Form for edit: how to manage access, security issue

I have a table Psychologists. Every psychologist has several clients. So it’s 1-to-many joint.
I want to add a link to the Airtable interface for editing for Client item, which open MiniExtensions form for editing.
What problem I have:

  1. When I turn on login it doesn’t work, because of 1-to-many joint (open always first client of the psychologist, but not which I want to edit)
  2. When I turn off login, every Edit button opens the right form, BUT it becomes UNSECURE, because this link can open and submit anyone

I saw How-to, but it’s out-of-date, Miniextension interface changed

Hi there, thank you for reaching out!

Could you please clarify your use case a little bit for me? Are the clients themselves making the edits, or is it the psychologist editing client records?

Thank you in advance for your cooperation!
