The only advantage that the Connect Bridge would give you, is that you will receive information on the Operator who opened the lock, if that model supports that.
Code management wasn’t the purpose of the integration as I recall, but rather to be able to add it to Home Assistant and control from it (lock/unlock). But @bdraco can correct me if I am wrong.
Do you have DoorSense? Then it would tell you if the door is open or closed.
Maybe discuss your question and issues in this topic, the user seem to have a similar lock as you.
For code management it seems you can use the Z-wave module.
No worries. Yes, that one is a quite complicated one, as there are multiple options. But you need to understand that Yale/August sells products in multiple continents with different product ranges and communication protocols. Including Bluetooth, Zwave, Zigbee and throught the Connect Bridge - Wifi as well…
Edit:
Maybe this discussion will help as well:
