You see here, I have created a platform function with expect fun, and I gave it the composable annotation. This makes it a Compose Multiplatform function, so then we can actually make this call from Compose code and also take advantage of some of the Compose methods. So we're going to use this expect fun to create a function interface that we satisfy with a different Kotlin function for each platform, so let's take a look at Android here.
