Remove / Move Outlook "App Bar"

Today my desktop Outlook application was updated and a new "App Bar" was moved to the left of the screen, previously it was located under my folders list with small icons and took up zero screen real estate, not so anymore.

Now it appears as a full screen height column with medium sized icons to the left of Outlook and it takes up way too much screen real estate, on my screen only about 15% of it can be even used with "app" icons pinned to it, the rest is just grey wasted space that takes away from the main job of Outlook reading/writing emails.

Is there a way to move this app bar, remove it, or at least minimise it to somewhere that doesn't use up so much space.

What's the reason for Microsoft to try and replicate a poor version of the Windows Start Menu within Outlook, one that's only limited to 3 Microsoft apps, I don't get this and would really like Microsoft to stop messing with UI, Windows 11 taskbar ahem.
