[2022] Why aren't any challenges showing up?

Hello everyone.

I started to play just a few days ago, so I have no idea if I'm not being an idiot, but I can't seem to access the Daily/Weekly challenges. It just shows a blank page on the right side where, I suppose, the challenges should be (viz picture)
Is it a bug or is it bound to something I have to unlock first?
Thanks for advice
