ho to RE-view the QR-Code after already added a child-Bridge into homekit
### Current Situation

when i add a child-bridge to homebridge i get a qr-code initially shown on the UI.
After adding this childbridte a am not able to review this code.
I need that code if i - for example - deleted the bridge in homekit for serveral reasons (i.e. deleting it becaus i have to setup homekit or the seperate bridge again)

When i try to see the qr-code again, there is only a text that says "coupled bridge" and a switch to turn it on or off.

How is it possible, to view the qr-code again in homebridge?

Thanks in advance
