Starting with Safari on iOS 13 browsers require sites to be served over https and request user permission to access DeviceOrientation events. This component presents a permission dialog for the user to grant or deny access.
The device-orientation-permission-ui component applies only to the <a-scene> element
To configure the style of the dialog one can redefine the associated css styles. To change the colors of the allow, deny and ok buttons:
.a-dialog-allow-button { background-color: red; }
.a-dialog-deny-button { background-color: blue; }
.a-dialog-ok-button { background-color: green; }
The dialog can also be disabled all together if you prefer to handle the permissions workflow differently.
