Convex Auth + Google + Custom Domain

Hey Convex team, I've configured Convex Auth with Google and it works great, except my Convex 
.site
 domain is being used even though I have a custom HTTP Actions domain configured in both Convex and Google Auth Platform.

The Convex URL shows up in the Google sign-in page, which makes it look untrustworthy to my customer (see screenshot) -- I need this page to display my custom subdomain instead.

I tried editing the 
domain
 value in my 
auth.config.ts
, but this doesn't help -- it seems 
process.env.CONVEX_SITE_URL
 is hardcoded in several places.

I couldn't find any places where that 
domain
 variable from 
auth.config.ts
 is used in 
convex-auth
, but I did notice it shows up in the Convex Deployment Settings UI under 
/settings/authentication
 . Would it possible (and would it fix this) to use this 
domain
 value instead of the hard-coded 
CONVEX_SITE_URL
 in 
convex-auth
?

The setup script already auto-populates 
domain: process.env.CONVEX_SITE_URL
 in 
auth.config.ts
, so it shouldn't break anything.

Thanks in advance,
Charlie
