Multichoice form element : select min max limit

Hello,
Topic : In form element’s video tutorial, it appears that the multiselect limiter (min max values) once exist in the available options of multiple choice form element settings.

I really appreciate Torro Form plugin but was unable to find this option in the last version i downloaded. Can you tell if it can be a misconf problem on my side or if this option was deprecated if not supressed in the last Torro Forms version. If yes, how to access this option in case it’s still possible? If not, is it accessible in a previous version or how can i implement this function?

yours.
