## Description
This PR will fix an error `TypeError cannot read properties of undefined
(reading '$el')` with the keyboard shortcut `Alt+KeyA` for triggering
the file picker.
**Issue**
I couldn't able reproduce this issue. It might be because `$children`
was unavailable at the time of access.
**Solution**
Previously, it relied on `$children`. Now, it uses the more reliable
`querySelector` method to find the target element.
