Support targeting self-hosted instances

[twoodhouse]

I've followed the instructions listed here to set up codeium with jupyter lab/notebook targeting a self-hosted instance:
https://codeium.com/jupyter_tutorial?audit=true

First issue:
"Get Codeium Authentication Token" button is not capable of pointing to the self-hosted instance. It always points to codeium's cloud instance, even when I have the target instance overridden in settings.

Second (larger) issue:
When I type in the editor, in browser network tools I see the following error being returned by our instance:

metadata.api_key: value length must be at least 1 characters [string.min_len]

Here's my codeium version. It is pretty new. Possible there was an API change that broke this plugin?
Codeium Docker Compose App Version: 2.9.4
Codeium Version: 1.24.0
