Building bridges is currently a two step process. First you must add the bridge you want to Bridgehub.
This allows you to configure the bridge to connect to whatever system you have an adapter for.
And set up the specific connection rules so, potentially, all environments could leverage the same bridge. Or perhaps you want to restrict connections to just one environment. Whatever you need can be set up for the bridge connections here.
Here you are building the half of your bridge between your platform and the sytem you are connecting to.
The second part of building the bridge is to set your platform front end to connect to that new bridge in bridge hub.
This portion of the set up is basically building the half of the bridge between your platform and Bridgehub, thus completing the bridge between the platform and the system you are connecting to.
