Doubling clicking the appimage did not work so I tried the following commands
chmod +x .appimage
sudo ./.appimage
but it gives me the error
dlopen(): error loading libfuse.so.2AppImages require FUSE to run. You might still be able to extract the contents of this AppImage if you run it with the --appimage-extract option. See https://github.com/AppImage/AppImageKit/wiki/FUSE for more information
but Fuse is installed in my system.
