Can't activate 1Password 8 SSH desktop app (Beta)

Hi all!
Need advice and direction to understand where I was wrong?

Try to add "beta.ssh.enabled": true in settings.json according this instruction - https://developer.1password.com/docs/ssh/get-started/#before-you-get-started

But my file, apparently, is not quite the one about which it is written in the instructions.

This is what inside my file.

Help please...

1Password Version: 8.6.0-26BETA.99918

OS Version: 12.2.1 (21D62)
