Keep screen on for specific apps, S25

Does anyone know if the Galaxy S25 has a setting to prevent my screen from turning off, but only for specific apps? This seemed to work on my S22, but I haven't found the S25 equivalent.

For example, if I'm watching a reddit video and it's coming up on 1 minute, my screen dims and will eventually turn off. In most apps, that's fine, but I don't want that to happen when I'm on Reddit.

Any thoughts on how to do this?

(And reddit specific, does this already happen if I click on the video? Instead of just watching it from the feed infinite feed?)
