[Android] [Firebase] Deleting a specific database

Hello.

I'm opening a chat room through Firebase

I want to delete the red part when I press a specific button

But when I press the button, the chat table is all erased.

Is there a way?

Please refer to it Crying.

firebase.database.ref().child('/chat/o').set(null);

I think we can do it like this. And the original firebase seems to automatically clear the parent node if the child does not have a valid node.
