How could I save skp 2025 to an earlier version

I need to save a SketchUp 2025 file for my colleague, who uses SketchUp Pro 2024, can open it. What’s the easiest way to do that? Why is there no longer a “Save As” option to select an older version?

This was explained long ago. A search of the forum will turn up several threads on the topic.
