Smartform submit?

I have setup recipient email (with verification finished) but form wouldn't submit to registered email

Using cleansky theme. Haven't edited the default contact form apart from switching to smartform (under form option)

am I missing additional step?

Upon further research, I noticed that my project folder is lacking [smart-forms.min.js] file. Deleting and recreating the smart form didn't add the specified file. Any way to add this manually?
