Add notification when deleting an accessory
### Feature Description

### What is happening?

When deleting an accessory in the plugin config, there is no notification or confirmation. If you have a large number of accessories and you delete one accidentally, you may not notice it.

Also, after deleting an accessory, closing the plugin configuration will not "save" the deletion to the `config.json`

### What you expect to happen?

When deleting an accessory, a notification (a toast?) is displayed, indicating that the accessory was removed. To confirm the deletion, press the `Save` button. To undo, press the `Close` button.
