Of course, you need to remap the buttons with a 3rd party utility first in order to assign the buttons to keyboard keys since those controllers were designed primarily for Android devices. Unfortunately there are no tools for IOS do stuff like that.
But with a little googeling, you will find lots of software to do so in windows. I even managed to use my 3dconnexion cad controller to work as a joystick (awesome for games btw.) and then using it to send midi and cc commands
I tried to find a software (i removed the old one quite a while back) and check it for you but for strange reasons my linkbox is not working for external bluetooth controllers since broadcom removed the win10 64 drivers. (btw if anyone found a workaround to use the linkbox's integrated BT again pls let me know) so i can't pair general BT devices right now.
So you already managed to get the device pop up in windows? You should be good then.
Try "Antimicro" (lots of tutorials on YT) to remap as you like
You only need to find out which button is sending what, because even if your functionality is limited "out of the box"
the other, for now, non-functional buttons send commands. After that, you can freely assign keyboard keys or even macros.
Keep in mind that it won't do any tracking stuff of course, so software that relies on that won't work of course.
But anything working with keyboard an mouse/ normal controllers should work fine.
