Hi, I need to disconnect a public account from our Open Account. I attempted to do this using the  https://developers.weixin.qq.com/doc/oplatform/openApi/OpenApiDoc/openplatform-management/unbindOpenAccount.html API, but it returned an error (89003). It seems we can only remove public accounts that were created through this API. However, the majority of our customers come from QR code scanning. How can I unbind those accounts? given account has 5 accounts integrated but we need to remove 3 of them.

您好，我需要将公共帐户与我们的开户帐户断开连接。我尝试使用 https://developers.weixin.qq.com/doc/oplatform/openApi/OpenApiDoc/openplatform-management/unbindOpenAccount.html API 执行此操作，但返回错误（89003）。看来我们只能删除通过此 API 创建的公共帐户。然而，我们的大部分客户来自二维码扫描。如何解除这些账户的绑定？给定帐户集成了 5 个帐户，但我们需要删除其中 3 个。
