Macbook Pro M1Pro doesn't recognize 3rd party keyboard layout

I did read about the "pc" versions Apple provides, and indeed no luck finding one for danish. I guess I shouldn't be surprised, there aren't that many users in this small a country so the demand is probably low. I'll link an image of my keyboard. The blue artisanal keys with icons are actually ecs in the top left corner with the key for $ and § bellow it. the key on the right side of the backspace is home. Thank you for helping.

I hope this serves as good enough an explanation, I just went over all keys to make sure I identified the problems. I'll link an image of what the keyboard viewer shows the layout to be, which is exactly how my macbooks build in keyboard looks. An this doesn't match the connected 3rd party keyboard. I've tried drawing in on an image, where the issues are.

First of the Fn function key doesn't react at all and the keyboard viewer doesn't show any key presses, therefore using the top f-row also doesn't do anything. Then it switches the key above tab (§ $) with the key to the right of left shift (> <). The right alt key on my 3rd part keyboard is shown in the viewer to be taking up the space of the right option key, but when pressed, it functions as the control instead.

The key left of the top part of my enter, types entirely different symbols when pressed together with control, compared to when I hid the buttons on the macs build in keyboard. Of course as you can see on the pictures, the row to the right of enter with page up and all aren't shown in the viewer, but I don't mind that as I never use them.

I hope my explanation makes sense.

Hi Tom.

I tried following the guide, but with no success, I'd rather not download a 3rd party app, like Karabiner, that makes deep changes in my device. So I tried writing the company behind my keyboard and am now waiting for them to reply. If that doesn't work either, I think I'll try and buy a normal none mechanical mac keyboard and see what happens, I don't mind spending the money if it's the easy solution, I'm not really a tech-guy. I guess this is kust the consequences of speaking a language with some extra funny letters, haha.

Jokes aside. Thank you for your help, I at the very least got some valuable inside as to where to look for issues and this certainly hasn't changed my mind if switching to mac was a good idea, it's way more comfortable working with mac as a graphic designer.

If I don't forget it, I'll post an update on this thread of whether the producer knows a solution or whether I bought a new.
