Using Hubitat with 2 Lutron Smart bridge pros (caseta) and trying to connect them to Smartthings using HubConnect

Can't seem to get this to work sadly. Newbie here. I have Hubconnect communicating back and forth with Smartthings/Hubitat and HubConnect has Hubitat as the Server. I thought they could communicate with each other this way. But seems that Smartthings is not recognizing any Lutron caseta dimmer switches in its smartapp. Smartthings is the remote client. I enabled the dimmer switches in Hubitat to communicate but nothing shows up in smarthings smartapp. No devices...

Sorry if this sounds confusing - I am a bit new to all this. Just trying to use 2 lutron smart bridges and smartthings doesn't make that possible. Tried just going with Hubitat but it's causing me so many headaches at this point - just trying to get something to work here. :slight_smile:
