Helium Browser rejected by 1Password BrowserSupport with browser mismatch

Hi, I’m trying to use the 1Password extension in Helium Browser on Windows 11, but it won’t connect to the 1Password desktop app. The extension shows “Integration status: Connection problem” even when the desktop app is unlocked.

Details:

Windows 11 Pro 25H2, build 26200.8655
1Password for Windows 8.12.22
Helium 0.13.3.1
1Password extension ID: aeblfdkhhhdcdjpifhhbdiojplfjncoa
Helium path: C:\Program Files\imput\Helium\Application\chrome.exe
Helium publisher: imput LLC

Relevant BrowserSupport log:

Verifying browser "C:\Program Files\imput\Helium\Application\chrome.exe"
name: chrome, publisher: imput LLC, version: 0.13.3.1
Browser support error: BrowserVerificationFail
Additional error context: browser mismatch

I reported this to Helium here: https://github.com/imputnet/helium-windows/issues/293

Their maintainer closed it as not planned and said this should be reported to 1Password. They also confirmed Helium’s executable is named chrome.exe for historical reasons, though changing that would require investigation on their side.

In 1Password, Settings → Browser does not show an Add Browser option, so I can’t manually trust Helium. Is there a supported way to add/trust this browser, or is the chrome.exe + imput LLC publisher combination currently blocked by 1Password’s browser verification?
