It's there a phone case for fp4, that covers up cameras for privacy reasons?

[Kah_Wai_Au]

I would like to have a phone case for my fp4, which covers up both selfie and main camera for privacy reasons. Somewhat like this:

I’ve seen some cases for popular Asian brands or apple devices. But the only results I get from searching are attachable slide stickers, than you can easily lose.
Thanks
