I installed Slimbook battery so I could manage my laptop's battery better than with the tools provided in the system settings, but I am unable to add the icon to the tray for better access (rather than going to Applications > Accessories > Slimbook battery preferences and then having to type my password).
Has anyone encountered some similar issue and found a solution? I'm running elementary OS 5.1.7 Hera, everything up-to-date. I tried installing gnome-shell-extension-appindicator
and rebooting. Typing in the command to start slimbookbattery writes that it is already started/executed.
