Trash icon
Use the icon for cases where you want to delete or remove the item permanently. This means there is almost no way to restore the item, even if there is an undo action after deletion.
Close icon
Use the icon to close or remove items from the interface. In this case, removal is not definitive, and the user can bring the item back even if they lost the original setup.
View off icon
Use the icon for cases where the user can temporarily hide some part of the interface. In this case, the show action should make it visible again.
Disconnect icon
Use the icon for the case user can disconnect the item from the platform, e.g., profile, but they can connect it back again.
