How to link to Google Sheets with edit-protected checkboxes?

Question

Google Sheets

The situation is this, there is a Google table with checkboxes (checkboxes), you need to do so that

1. Those to whom I will throw off the link to the table could check the box once (cannot be changed)
   
2. You can't uncheck it either.
   

So far, I've just tried to protect the range, but then the checkboxes cannot be set to a third-party user.
Who has any ideas?

Answer 1

There is no such functionality. Let your users check boxes in Forms.

Answer 2

You can pervert and add an onEdit () handler, where you can put protection on the checkboxes and remember users separately. But it will be difficult and unreliable. Google Forms will indeed be the best solution.
