Welcome Tiago212,
Thank you for using Apple Support Communities. Based on your post, you're missing the translation button within the Safari app for Mac. We'll do our best to help out.
Given your screenshots, it appears that Safari is successfully translating the website that you visited (Apple's site), is that right?
In the Smart Search field, we see there are is another option at the right side with three dots. When you select this, what options do you have exactly?
Are you running Catalina, Big Sur, or Monterey on this Mac? Are you using Private Browsing at all?
This might be able to explain how to use the feature: Translate a webpage in Safari on Mac
Hoping to hear back, take care.
