How do people do -Xopt-in=kotlin.RequiresOptIn in multiplatform projects? IntelliJ annoyingly keeps asking me to add it but I have.

targets.all {
        compilations.all {
            kotlinOptions {
                freeCompilerArgs = listOf("-Xopt-in=kotlin.RequiresOptIn")
            }
        }
    }

Turns out this worked.

sourceSets.all {
            languageSettings.useExperimentalAnnotation("kotlin.RequiresOptIn")
        }
