Add permission settings when sharing workspace/private posts via link

[hhhguany]

Describe the solution you'd like

After setting a post as a workspace or private, we may want to share it with specific external users. In this case, we need a feature that allows us to select access permissions when sharing (currently through copying a link), such as allowing everyone who gets the link to view it.

将一个帖子设为工作区或者私密后，我们可能想要与特定的外部用户分享。在这种情况下，我们需要有一个功能，在分享时（现在是通过复制链接），可以选择访问权限，比如允许获取链接的所有人查看。
