1Password doesn't work in my Brave web browser

@Joy_1P Still doesn't work.

The 1Password icon in the tool bar shows it as still locked even though I have launched and unlocked 1Password.app first:

Clicking on the toolbar icon opens this window:

but nothing happens when I click on the "Open 1Password" button.

I still tried it out but 1Password never activated in Brave.

BTW, I'm using the MacOS version of 1Password so the text is slightly different from what you wrote in the "Turn on..." paragraph above.
In step 2, it is Preferences instead of Settings, and in step 3, instead of the word "Keep" it is "Show".
