Bitwarden extension icon not showing in Brave on Mac

I have just installed the Bitwarden extension on my Brave browser, but the icon does not show up as expected in the browser. The extension is shown as enabled in Brave extensions.
The Bitwarden extension icon does show as expected in Safari. The computer is running macOS Ventura, and Brave is the latest version.
Any suggestions as to how to proceed?

I seem to recall having to “pin” the icon in Chrome to make it permanently visible. I know Brave is based on Chrome so could be a similar issue. Click the plugin icon.


Perfect, thank you.
