Controlling Two Lights with One Switch? Need Help!

Hey everyone, I’m trying to set up my smart home and have a question about controlling two lights with one switch. I have a HM-LC-Dim1TPBU-FM switch that currently controls my ceiling light. I’d love to use the same switch to control another light using an UP-Dimmer HM-LC-Dim1T-FM. Is this possible? I’ve tried setting up a direct connection, but the switch channel doesn’t show up. Am I missing something? Any advice would be super helpful! :blush:
