What are SDG Tags?

Just noticed there is a new field when creating surveys called “SDG Tags”. The field has the helper text that says “Select one or more tags”.
Is there information somewhere that explains the purpose of this field and what sort of entry it is looking for?

Hi Frank,

That field was not supposed to be visible to users yet and it has been hidden again. It’s a new feature we’re working on - you accidentally got a sneak preview. More info coming soon!

All the best,
Sara
