How do I seamlessly take higher-resolution screenshots than what the display supports on KDE Wayland?

I am trying to take a high-resolution screenshot of an app. I want the screenshot to have more detail than what my display supports but I can't seem to find a seamless and easy way to do that. What I Have Tried: 1. KDE Built-In Scaling: This works well for taking higher resolution screenshots, but isn't really seamless as it increases the size of the window and I have to set it back to the default once I have taken the screenshot. 2. Using gamescope: I tried using gamescope to run KDE at a higher resolution and scale it down but couldn't get it to work as it always resulted in a black screen.
