twitch-indicator not being detected

### Specifications
- Hardcode-Tray version : `4.3`
- Distribution : `Arch Linux`
- Gtk version : `3.24.43-4`
- Inkscape version : `1.4`
- Application name : `twitch-indicator`
- Application version : `1.8-2`

### Expected behavior and actual behavior
Expected behavior: `twitch-indicator` to be detected and the icon to be replaced.
Actual behavior: Only `Steam` is detected and its icon is replaced.

### Steps to reproduce the problem
1. Run `sudo hardcode-tray` or `sudo -E hardcode-tray`
2. Select `1 - Apply`
3. Only `Steam` will be found and applied

#### Alternatively:
1. Run `sudo hardcode-tray --only twitch-indicator`
2. Select `1 - Apply`
3. Output will include `No apps to fix!`

`twitch-indicator` is installed via AUR. I've tried installing `hardcode-tray` via AUR both through `hardcode-tray` and `hardcode-tray-git` as well as a manual install after cloning the repo (doing a `sudo pacman -Rns hardcode-tray` to remove the AUR ones before moving forward.)

Start by running `hardcode-tray --only twitch-indicator` and compare its detection result with the existing Steam behavior. Trace the application-detection path to determine why `twitch-indicator` is skipped. Done means the application is detected and its icon is replaced without breaking Steam handling.
