What is the replacement for the xwd utility (X Window Dump) with Wayland (or even RHEL9)

I have old software that uses the program xwd to save graphics files (to make movies, or figures in papers). xwd exists as a utility in RHEL8 (and Rocky Linux 8) but in Rocky Linux 9 (and one presumes RHEL9) this no longer exists. Under Wayland, it appears this is going to be not available at all (as it's a security issue?) I'm guessing there has to be some way (hopefully not Gnome, KDE, or... specific) to save a graphics image of a window. Is there a generic "replacement" for the functionality of xwd? To be clear, I'm still using X11 on RL9, as I'm also using NVIDIA's gpu libs. But I will eventually need to get this working on Wayland also.
