I cannot play Halo Wars DE?

I bought Halo Wars 2 digital in order to get Halo Wars DE, after buying it, on my Games and Apps, it featured Halo Wars logo but when you open it, it sends you to Halo Wars 2 Blitz Beta.

How can I play Halo Wars DE? I thought you can instantly play after buying it??

Help!

There’s more information in the pinned threads here about HW:DE codes

Essentially you need to wait to receive an early access token for the game, although you can reach out to Xbox Support as well as noted in the FAWs
