Related to Starship: Battery module is disabled in resolved config, even if toggled in custom config issue.

Environment

• Operating system: Pop!_OS 22.04
• Terminal emulator: GNOME Terminal 3.44.0 using VTE 0.68.0 +BIDI +GNUTLS +ICU +SYSTEMD
• Git Commit Hash:

I believe I've located where the problem might be coming from:

I found some related sources. It's interesting to know what's happening under the hood, especially because upower is giving me the right information...
Command:

$ upower -i $(upower -e | grep 'BAT') | grep -E "state|to\ full|percentage"

Output:

    state:               discharging
    percentage:          92%
