Confusion concerning Windows 11 Activation

I recently downloaded the Windows 11 Insider Preview with Parallels and have been prompted to activate windows a few times. I'm really confused as to how to go about this. I can't find any activation codes and have even found some information stating that a preview build cannot be activated. I have tried finding the Windows 10 preview, as I can find Windows 10 keys, but it seems to have been removed from the Microsoft website. Upon researching all of this for hours, I have not come upon any particularly productive answers. Any help would be greatly appreciated!

 

Insider builds can be activated with a 10 pro/enterprise license key. All it will do is stop the nagging and open more features but you should still be able to use it without activating
