Remote clicker for iPad

This question has been raised before. I'm not sure what makes it so difficult to find a remote that works with the iPad, but I've purchased several that claimed to work - none did, and all were returned. The problem may be that the people who design the clickers don't actually know what a presenter needs. I won't call out brands,

There are several remote clickers that claim compatibility with Pads (one specifically citing my current iPad model (Air 4th Gen, 2020). With PowerPoint or Keynote in Edit mode you can navigate around the app menus , but clicking when a menu item is highlighted doesn't activate the menu item - you have to tap the iPad screen. Some also have an airmouse-type cursor function, so you can activate edit-mode menu items by getting the cursor on the item and clicking. Why anyone would want to edit a presentation remotely while waving the remote around to try to click on a menu item I have no idea. And in presentation mode? Well clicking on the remote will advance the slide; but moving back? None of these devices have a Back button (and the navigation buttons don't have that functionality).

I did find one device (well-known brand) that looked promising, with software that allowed buttons to be re-assigned to different functions using an app from the manufacturer. The remote without the app behaved as all the previous items I've tested, so I went to the website and tried to download the app - available for MacOS, iOS and...not for iPadOS.

I'm waiting for another remote from the same manufacturer that has a Next Button and a dedicated Back button. The info sheet says it has limited functionality on iPad OS without the software, but I'm hoping that if there's a dedicated Back button it'll be a default function and won't need additional software. I've also read that enabling AssistiveTouch in the Accessibility menu might be required.

I'll update this if I have any success...
