CUSTOM KEY VALIDATION

I've created a custom key, but it doesn't validate if there are staged changes. It executes even if there are no staged files. Any help would be appreciated.

Here's my custom command configuration:
```yaml
gui:
nerdFontsVersion: "3"
customCommands:
- key: ""
context: "files"
description: "Commit with Gitmoji 👽"

prompts:
- type: "menu"
title: "Choose a Gitmoji"
key: "Gitmoji"
suggestions:
preset: "branches"

options:
- name: "✨ feat"
value: "✨"
- name: "🐛 fix"
value: "🐛"
- name: "📝 docs"
value: "📝"
- name: "💄 style"

initialValue: ""
- type: "input"

key: "CommitDescription"
initialValue: ""
checkForConflicts: true
command: |
staged_files=$(git diff --cached --name-only)
if [ -z "$staged_files" ]; then
echo "No files staged for commit. Please stage your changes first."
exit 1
else
git commit -m '{{.Form.Gitmoji}} {{.Form.CommitSummary}}' -m '{{.Form.CommitDescription}}'
fi
