How to control smartthings bulbs (non ikea) using IKEA tradfri dimmer

I am able to connect the dimmer to Smartthings hub. I have many Osram sylvania bulbs connected to smartthings hub as well. Anyone know how to use my ikea dimmer to control the bulbs connected to smartthings?

Sorry if it is posted somewhere, i searched but couldn’t find a solution.

Anyone able to help?
