RPI Imager 2.0

see a video about RPI Imager 2
and want to try:

from https://www.raspberrypi.com/software/
using Ubuntu 25.10 PC
get imager_2.0.0_amd64.AppImage 38MB

now i not know how to install it from there??

sudo apt install rpi-imager gives me v1.8.5

app center install gives me additionally v1.9.3

OR to run above AppImage

try from commandline:
cd Downloads
sudo ./imager_2.0.0_amd64.AppImage
here it fails:

-a- make it executable
chmod +x imager_2.0.0_amd64.AppImage

-b- if lib missing:
sudo apt install libfuse2t64

-c- if OpenGL error:
sudo apt install libopengl0

now it starts!
BUT THAT I NOT CALL A INSTALLATION
