Preheat oven to 325°F; line a baking sheet with parchment paper.
Using an electric hand mixer, beat egg white on medium speed until medium peaks form, 2 to 3 minutes. Fold in the coconut, followed by condensed milk, salt, Coconut, Mango, and Tahitian Bean Flavours, just until combined.
Drop 2 tbsp of mixture 1-inch apart onto the prepared pan. Using fingers, gently shape into peaked mounds. Bake until golden brown, 15 to 16 minutes. Let cool completely on pan, about 15 minutes.
Chocolate Coating: Place chocolate in a bowl set over a small saucepan with 1-inch simmering (not boiling) water and melt, stirring every so often. Remove bowl from heat and stir in coconut oil.
Dip macaroons in chocolate to coat base and edges; return to parchment. Refrigerate until chocolate is set, about 15 minutes.
