Are you in the US? If so, probably the easiest way is to get the Lutron connected bulb remote. It can reset individual bulbs. You can get this at Home Depot for $30. (note that although the lutron device can be paired to the smart things hub, it will not stay paired. So you won’t be able to use it as a remote with the SmartThings system unless you’re willing to keep pairing it again every few days. But you will be able to use it to factory reset individual bulbs.)
