access XRHelpURLConstants.k_TeleportationArea from script in unity 2022

I updated my unity project from 2020 to 2022 and now I get on this code:

[HelpURL(XRHelpURLConstants.k_TeleportationArea)]

this error:

XRHelpURLConstants is inaccessible due to its protection level

Since the class is not public, how to access this from another class?
I am a little bit confused
