Question regarding prerequisites for Cloud Backup

Hey everyone, I was looking into some specifics regarding savesystems with quest and have a question, perhaps someone can clear things up for me.

So I understand Meta has moved away from a cloud storage API to use Androids automatic cloud backup system. I wanted to test that out with a Unity app I made.

From what can see there are mutliple steps that need to be setup for sure:
- In the App created on the meta developer dashboard, cloud storage must be activated
- The User (in this case myself) must have cloud backup enabled on the headset itself

Those 2 seem quite certain. Now there's one third thing that I'm trying to find out: OculusProjectConfig.asset and it's "disableBackup" flag. This will set the resulting Manifests allowBackup flag from what I gather, but not 100% sure even on this

I had written a large paragraph trying to explain what got me confused, but I'll ratehr just ask outright: Is it a necessity to also make sure that the allowBackup flag in the final AndroidManifest is set to true?

Thx
