我想在我的帖子灵活内容字段中添加一行。我使用导出工具中的代码创建了我的 ACF 字段，这是其中的一部分：

当我创建或编辑帖子时，我可以看到和使用这些字段。现在我有一个脚本来导入帖子，我想以Tekst (1 blok per rij)编程方式将该字段添加为新行。我试过使用add_sub_row，update_field但没有一个能正常工作。
当我add_sub_row这样使用时，我总是得到一个返回值false：
add_sub_row([ 'field_5c4a0645c3baa', 1, 'field_5c4a0666c3bab'], [
'field_5c4a0666c3bab' => 'test'
], $post)
当我使用时，update_field我确实得到了一个响应，看起来好像该字段已添加，但是当我去 wp-admin 并打开帖子时我看不到它：
update_field('field_5c4a0645c3baa', [
'acf_fc_layout' => 'text',
'text_content' => 'test'
], $post)
我应该如何使用这些方法？因为我尝试过使用 ACF 的手册，但我真的不明白如何将它用于灵活的内容。
