Confused by F12 can't render

Support Compositing and Post Processing

I have a basic comp. Looking at the output mode, I can see folder output but I don’t see a “render” button to render the output.

Thanks.

Never thought about that, always used F12. I think the button was useless and gone since 2.8 (?), but there is everything in the GUI: Menu Render → Render Image (F12)
