Level 2 Spam Check

On the description page given for Extended version it states:
“Added 2 level spam check. If you are still getting spam submission, you can enable 2 level spam check in Extended version from Extended Settings tab.”

I’m using this activated version and I cannot locate the Extended Settings tab. We’re not instructed on where it is found and I don’t see it anywhere on the dashboard or elsewhere on the plugin’s home page dashboard https://dineshkarki.com.np/wp-admin/index.php. It’s either well hidden from me or unavailable. HELP!
