Show Assignee of Subtask on Card. #2

I wanted Subtask assignee to show on the board

I copied this from /app/Template/board/tooltip_subtasks.php LINE 14-20
Inserted below LINE 11 in /Plugins/SubtasksOnBoard/Template/board/subtasklist.php
<td> <?php if (! empty($subtask['username'])): ?> <?= $this->text->e($subtask['name'] ?: $subtask['username']) ?> <?php else: ?> <?= t('Not assigned') ?> <?php endif ?> </td>
