Read it on reddit. Basically create a new PSN account and select Singapore as the country. Then search for WWII on PS Store and select 'PreOrder'. Scroll down and select the private beta and it should then download.
Cheers
PS: You can make the Singapore account primary and play the beta on your main account. This also works for many other betas
