Need help with reassembling wireless controller

Can anyone please help I have a 10 button Demag wireless controller sitting on my desk and all the springs fell out along with the magnets for the Hall effects sensors.

I can’t find a service manual, I have talked to someone who I understand to be a rep and they knew nothing about them nor could they find me any technical information.

I’m getting very confused by what I find on line or what AI is telling me.

There are two different length (same diameter) springs and I’m not sure which buttons they sit under.

I’m also not sure I have orientation of sensor magnets correct.
