Outputting a formula as a checkbox

[Gingermatti]

Hoping someone can help, I saw in Airtable's 'What's New' update in July that if a formula returns "a boolean (true/false), a new formatting option lets you output the result as a checkbox instead of a number". 

This would be really useful for me, but I have tried multiple ways to do this and have not sound it possible. I know Airtable's checkboxes mostly use 1 for checked and 0 for unchecked, so have tried outputting formula as a 1 or 0 for true / false, but no luck (tried "1" / "0", "true" / "false" etc too). Here's the screenshots from the 'What's New' page, if anyone has had any luck with this, help would be really appreciated. 

Thanks

Matti

Yeah, it’s odd that Airtable doesn’t explain this anywhere. Your output either needs to be TRUE() or FALSE()
