How to delete entity node completely from Bot Builder?

Hi, I am new to development. I just want to know from where I can delete an entity node completely from the Bot builder? Now, once an entity node is created, I can delete it from a dialog task flow. But it will be still there in the back-ground. I need to know the place from where I can manage all the entities created.
Please help.

You can achieve it from Manage Components
Locate and delete the entity. It should show you where all it is being used. So please try to remove the usage first for clean removal.

Once you remove it, it will get removed only from in-development version, please publish the bot to fully remove it.
