Trying to consolidate wifi networks => Bridge?

Patrick Van Osta

I have a modem/wifi router on SSID ABC. I run an ethernet cable to a Mesh of Amplifi Cubes, broadcasting on SSID XYZ.

I would prefer running everything on SSID ABC, so I can also leverage my modem's wifi broadcasting capability.

What is the best way to achieve this?
Do I set the Amplifi Hub to 'Bridge'? Then what happens next? Or do I need to do something completely different?

I see the slider for Bridge, but I don't want to break something that will take me hours to undo afterwards, hence I prefer to ask here first.
Thank you for your input.
