[Bug] Auto Shift custom filter hjkl can not work

Describe the Bug

The Auto Shift feature is incredibly useful. However, it conflicts with long-pressing hjkl in Vim. I've tried modifying keymap.c, but it didn't work.

bool get_auto_shifted_key(uint16_t keycode, keyrecord_t *record) {
    switch (keycode) {
        case KC_H:
        case KC_J:
        case KC_K:
        case KC_L:
            return false; // disable Auto-Shift
        default:
            return true; // others Auto-Shift
    }
}
