URL Bar Visible on Additional Trusted Origin Domain in PWA APK

I'm experiencing an issue with my PWA where the URL bar is not behaving as expected across different domains. Here's the setup:

- My PWA is hosted on: `https://app.domain.com`
- My SSO (Keycloak) is hosted on: `https://sso.domain.com`

### Problem

When accessing the PWA on `https://app.domain.com`, the URL bar is hidden as expected. However, when the PWA navigates to `https://sso.domain.com` for SSO purposes, the URL bar becomes visible. I want the URL bar to remain hidden on both domains.

### Configuration

1. **Asset Links:**
- Both `app.domain.com` and `sso.domain.com` have the same `assetlinks.json` file with `no-cache` cache control, and they are accessible.
- The `assetlinks.json` file includes the necessary entries for both domains.

2. **HTML Head:**
- On `https://sso.domain.com`, I have included the following in the `` section:
```html

```

### Issue

Despite following the steps outlined above, the URL bar remains visible on `https://sso.domain.com`. I am unsure what might be wrong with the SSO additional trusted origin configuration.

### Request

Could you please help me identify what might be causing this issue or guide me on any additional steps I might need to take to resolve it?

### Additional Information

Let me know if there is any more information that I can provide to help diagnose this issue.
