Line a large baking sheet with parchment paper.
Pour tempered white chocolate (instructions below) onto prepared baking sheet. Using an offset spatula, quickly spread the white chocolate into a thin, even layer.
Immediately sprinkle on the okra, flax seeds, crushed raspberries, and papaya cubes evenly over the white chocolate. Gently press toppings into the chocolate. Let the bark set completely.
You can cut the bark into strips or squares, or break it apart into small or medium-sized pieces. Store white chocolate bark in an airtight container, at room temperature, for up to 2 weeks.
