Sci-fi sacrifice spacestation

remember watching a sci fi thriller at the cinemas in the 2010s

I’m pretty sure they’re in a space station or something trying to stop an explosion

I think they’ve been held hostage because in one scene late in the movie the main character speaks about a story about his childhood to his nephew who is watching on a live feed from the presidents office but it’s actually a hidden code so that he may decipher it and save them

At the end he sacrifices himself in the explosion to save the others

Hi, could it be “The Cloverfield Paradox” (2018)?
