No Push Notification Capability in Xcode

I don't know why, but the option Push Notifications of Capabilities in Xcode is not displayed. Why?

I follow the developer guides, creating cers, enabling push in provisiong profiles, etc.

I had refreshed the account in Xcode preferences. What I am doing wrong?

xcode

Can't find push notifications in capabilities in Xcode?

If the "Push Notifications" box is not appearing in that view below the signing section, that means you need to add it (it probably means your project doesn't have an entitlements file).

How do I enable capabilities in Xcode?

In the toolbar, click the Library button (+) to open the Capabilities library. Alternatively, click + Capability to the left of the build configurations, or choose Editor > Add Capability.

You need a apple account not free,Please see the picture:
