freshly installed ubuntu 22.04 (in a vm on a windows 10 host). session log:

ag@ag-VirtualBox:~/Downloads$ chmod a+x standard-notes-3.23.86-linux-x86_64.AppImage 
ag@ag-VirtualBox:~/Downloads$ ./standard-notes-3.23.86-linux-x86_64.AppImage 
dlopen(): error loading libfuse.so.2

AppImages 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

Please add a note in the installation page about dependency on FUSE.

Doing this worked:

sudo add-apt-repository universe
sudo apt install libfuse2
