Thank you so much for your quickly answer! I’ve wasted hours trying to make this code to work! Now everything is working perfectly. Thank you very much!
Explaining better: I tried to use shortcode and all the codes I found but the excerpt, date, author and categories do not appear. The code is not inside the loop, and my WP version is the last one (5.6.2). I also tried to disable some plugins, but it didn’t work well.
