Daily Fortnite Chores: Save the World Unlock?

I'm a beginner in RDW and I recently watched a guide on YouTube that reports on "Daily Challenges".

When I wanted to check what my daily challenges are, I noticed that I could not find any daily challenges under "Order description".

Do you have to unlock them first?

If so, when do you unlock them?

Or were they removed because they were too strong?

Please clarify me.

I only play online and there are daily challenges. Maybe he means that in the video? Or was it explicitly described on RDW?

Thanks for your quick answer, but my question has just been answered

You have to unlock the Daily Challenges first

Nevertheless, many thanks and you and your family Happy Easter and good health

Thank you too.
