Description of the hardware

I have a keyboard from Brazil, the layout is called abnt2 and it is a standard that many keyboards here use. for some reason there is no layout compatible with this standard in the keyboard configuration app.
after a quick search I found some people with the same problem, a quick solution is to type setxkbmap -model abnt2 -layout br in the terminal which seems to fix the problem. I can probably set up some script that runs this command every time I log in, but that doesn't solve the problem for everyone else.

here is a photo of a keyboard similar to mine here you can see an arrow that indicates a key on the keyboard, in all the layouts I have tested this key is not recognized.
