How to install this extension on Ubuntu 22.04?

Either installing using web browser or source code do not work. On "https://extensions.gnome.org/extension/3010/system-monitor-next/", it shows a note "Your native host connector do not support following APIs: v6. Probably you should upgrade native host connector or install plugins for missing APIs. Refer documentation for instructions.", which is confusing.

You may need to install the GNOME Shell integration browser plugin, or maybe already had but it's gotten itself misconfigured. I would recommend installing extension-manager & using that to browser for & install GNOME Shell extensions instead: sudo apt install -y extension-manager
