Showing a better onscreen keyboard on MacOS

I am looking for an old style onscreen keyboard. Is this still an option on MacOS, or is there a third party application? Or has it been there all along but I missed it? It used to look something like this: The current Keyboard Viewer (a) doesn’t show the extended keyboard, which I do have, and (b) is pretty ugly; no, it’s _very_ ugly. Among other things, I want to record keyboard activity for teaching purposes. I am using MacOS Big Sur. I have an Apple bluetooth extended keyboard. I don’t know whether the fact that I’m using the Australian keyboard is relevant. For clarification - Big Sur Keyboard Viewer vs Mojave Keyboard Viewer [both on Extended UK Keyboards] - the one accessed from the Keyboard/Language menu icon in each case. the Big Sur one now looks like the old Accessibility Viewer.
