Description of issue

Installing 1pass cli with homebrew (brew install --cask 1password-cli) works as expected, but trying to invoke the tool causes the OS (Ventura 15.5) to throw up a dialog box which says:

Apple could not verify “op” is free of malware that may harm your Mac or compromise your privacy.

Uninstalling and reinstalling does not help

When the cli is installed into /usr/local/bin using the .pkg from https://app-updates.agilebits.com/product_history/CLI2, it works without issue.

After manually installing, the homebrew installed version in /opt/homebrew/bin/ also works without issue.

I'm not sure if this is reproducible or if the corporate IT settings on my machine are causing this.
