Shortcode to “posts reply” in created theme

I trying to build a forum theme with divi, it is easy to create the theme for the general forum structure with the help of shortcodes
This is my forum

Forum

I can use the same theme for topics as well, as in this case:
https://www.aqazero.com/forums/forum/acquario-acquariofilia-%f0%9f%8c%8a%f0%9f%90%a0-aqa0-%f0%9f%90%9f%f0%9f%8c%bf/

Unfortunately, however, if I open the question (post) the theme is not inherited
https://www.aqazero.com/forums/topic/prova-topic/

Is there a shortcodes to display the question (post) and the area to reply (reply form)?

Thanks in advance for your answers..
