How can I access the user ID with the Discord Provider?

[PumPum7]

Hello,
This is my first time using this library and I tried to use the Discord Provider but for some reason I cant not access the user ID. I have also tried to change the profile function of the Provider but for some reason I can only remove information but I can not add additional information.
I have tried to log the user ID in the profile function which worked and the image URL generation (which uses the user ID) also works.
