Single post page display all posts after previous and next buttons

Hello again!

I would like to manage displaying all posts (like main page) after a post in the single post page (so we don’t have to go back to main page or chose between previous or next post).
Have some coding skills, and seen your hooks (more than sure that I’ve missed something…haha)
I’ve already tried some moves, but couldn’t manage to display more than the same post after.

Thanks for your time!
