[Feature Request] App lock

Is there a way for grapheneos to have this feature implemented in the future

Looki can you explain the feature?

I think it's a good idea, like MIUI does (and I think Samsung too)

spiral just being able to lock apps would be great especially messages or gallery for example

Looki ahh, like biometric/pin locking of apps?

spiral yes exactly something like that

Even though there are plenty of app lock apps, they are risked with ads and very slow.

I would love a native app lock with various locking options (separate from device unlock).
